a photon, has the helicity of it momentum, this can be righthanded or lefthanded. a neutrino is strictly lefthanded.

So?

Quote from: esquire on 13/06/2019 01:25:13
a photon cannot transverse matter in the same way a neutrino transverses matter, basically unobstructed.

That's because photons interact via the electromagnetic force while neutrinos do not. The electromagnetic force is much, much stronger and much, much longer-ranged than the weak nuclear force.

Quote from: esquire on 13/06/2019 01:25:13
the effect of matter on a photon is different then the effect of matter (energy'momentum}  on a neutrino,

Yes, because they interact via different forces.

Quote from: esquire on 13/06/2019 01:25:13
where matter, energy and momentum, have no effect on neutrinos.

They do have an effect on matter. If they didn't, it would be impossible to detect them.

Quote from: esquire on 13/06/2019 01:25:13
the fact that a higgs field also doesn't couple with a massless photon is not pertinent to a discussion about neutrinos.

It is if you claim that the lack of coupling to the Higgs field means that something is unaffected by gravity. Relativity requires anything with energy to respond to gravitational fields.

Quote from: esquire on 13/06/2019 01:25:13
please explain how neutrinos transverses the earth unaffected if they are under gravity's auspices.

Whoever said they travel through the Earth unaffected by gravity? Are you claiming that they should be captured by the Earth's gravity or something? They are moving far, far in excess of the Earth's escape velocity, so that can't happen. In theory, their paths should be deflected by gravitational fields in the same way that the paths of photons are deflected. However, detectors like IceCube aren't designed to look for neutrino gravitational lensing.

Quote from: esquire on 13/06/2019 01:25:13
photons have a wave property. i have not heard of neutrinos demonstrating a wave property. photons and neutrinos are apples and oranges. would you conduct an experiment on one element and declare the results pertinent for other elements?

You might want to read this: http://www.fnal.gov/pub/today/SpecialROWMINOS111408.html

Quote from: esquire on 13/06/2019 01:25:13
although the transmutations of neutrinos donot take place as nuclear transmutation, requiring excessive amounts of energy but rather they transmute Innocuously, depending on the local matter environment.

Radioisotope decay doesn't require "excessive amounts of energy" either. It happens spontaneously even when the nucleus is in its ground energy state.

I think the technical term you are looking for is "neutrino oscillation" rather than "neutrino transmutation".
- Unlike nuclear decay, neutrino oscillation is not a 1-way process, but more a quantum uncertainty about the "flavor" of a neutrino at any point in time
- Neutrino oscillation (or almost anything about neutrinos) is not greatly affected by its matter environment
- The symptoms of Neutrino oscillation were first detected as a shortfall in the number of neutrinos emitted by the Sun - they detected about 1/3 of the expected quantity. Eventually this was explained by the fact that 2/3 of the neutrinos produced in the Sun changed into other flavors of neutrino before they reached Earth, and were undetectable by this apparatus (very pure dry cleaning fluid). So the oscillation occurred in 150 million km of vacuum (not matter).
- More recent experiments conducted near nuclear reactors have been able to study neutrino oscillation in more detail, as the neutrinos pass through the air.
- For a visible photon, there is little difference between vacuum and air; for neutrinos, there is little difference between vacuum and the element Lead. So I don't see what difference matter makes (although I read that neutrinos may be affected by the Hydrogen core of the Sun, which is far denser than lead).
See: https://en.wikipedia.org/wiki/Neutrino_oscillation

neutrinos are only lefthanded chiral
In theory, Neutrinos must have the opposite chirality to Anti-neutrinos.

It is possible that neutrinos propagate as an oscillation of left and right chirality. If so, it's because they are traveling so close to the speed of light that very few Solar neutrinos have changed chirality before they reach detectors on Earth.

kidkrypt is the one that chose "nuclear transmutation" as a example in an attempt to prove particles change their elemental states. my original point was that neutrinos alter their states without an excessive amount of energy employed.

as a neutrino transverses different densities it does if fact alter its energy signature. this is the coping mechanism for neutrino coupling to  alter between it's three flavors.

the difference between a vacuum and air, and a vacuum and lead is substantial. this goes to the point that kidkypt was attempting to compare photon and neutrino, apples and oranges,  in an attempt to dispute my original point.

charge parity appear to be violated by neutrinos and anti neutrinos, as such, their properties are not reflective. this means they are incapable of an explosive interaction. this inability to interact,  again defies gravity.

the fact that neutrinos unlike particles can occupy the same point in space and time, again defies gravity. this excludes it from being a particle. if is not a particle and it is not a boson, the simplest solution is that neutrinos are holes in the fabric of spacetime. this implies that neutrinos and anti neutrinos pass though each other. 

please excuse any spelling or grammar issue, my  limitations  no longer cause me concern.

CP violation has nothing to do with gravity. Anything with energy (which would include both neutrinos and antineutrinos) can interact via gravity.

Quote from: esquire on 14/06/2019 17:33:18

(1) How do you know that neutrinos can occupy the same point in space-time? The fact that they have fractional spin (making them fermions) means that quantum mechanics would forbid such a thing from occurring.
(2) Bosons can occupy the same point in space-time, which contradicts your claim that this is something that particles cannot do.

Quote from: esquire on 14/06/2019 17:33:18

Whether or not something is a fermion or a boson has nothing to do with gravity. If it has energy, it interacts via gravity.

Quote from: esquire on 14/06/2019 17:33:18

Again, bosons do exactly that.

Quote from: esquire on 14/06/2019 17:33:18
if is not a particle and it is not a boson, the simplest solution is that neutrinos are holes in the fabric of spacetime. this implies that neutrinos and anti neutrinos pass though each other. 

So you think that holes in space-time (whatever that means) can have momentum, energy, velocity, spin and interact with the weak nuclear force? Because neutrinos have all of those things.

uranium 238 is transmuted by a fast neutron in a fission process, external energy required!. 

gravity is what causes the attraction between particles and anti particles, which result in an explosion.
neutrinos and anti-neutrinos don't interact a cp violation. gravity doesnot produce an attraction between neutrinos and anti-neutrinos.

neutrinos occupy the same spacetime location. a neutrino is capable of transmuting into a different flavor and reverting again. this transmution and subsequent reversion is one neutrino joining another to result in a higher energy neutrino.

a boson is not a fermion particle, it is a field within field, a wave within a wave. the higgs boson develops an energy signature as a result of a concussion, forcing a field inside a field. a boson is a force carrier (a field), a field by itself is not a particle, it is a component that comprises an elementary particle, field, energy and spin. not a particle in the sense of fermion particle. bosons are now classified as particle because not to do so, would refute the higgs boson's experimental finding of an energy charge signature. researcher are clueless to explain.

a field within a field, a wave with a wave, has no fermion basis. it is a charge devoid of matter, a hole with a spin. not bound by gravity,   not the first contradictory statement uttered in science!

bosons belong in the quantum realm, they are zero mass, zero charge, with a twist(spin)  i.e. a photon. zero mass = not a particle. a photon is a particle that lack a basis for it's charge! not at contradictory.

is the warping of space/time a homogenous feature without imperfections, some academics, obviously think so!

I'm not talking about nuclear fission, I'm talking about radioactive decay. Uranium-235 decays on its own, without any external neutrons required, with a half-life of around 4.5 billion years.

Not in most cases. Gravity is far too weak on subatomic scales for that to work.

This is the second time you've stated this non-sequitur. Gravity has nothing to do with CP violation.

Quote from: esquire on 15/06/2019 17:53:42

This is the second time you've made this claim without providing evidence for it. We know that two neutrinos can't occupy the same quantum state because they have a spin of 1/2. Quantum mechanics forbids it.

That would violate conservation of lepton number.

Quote from: esquire on 15/06/2019 17:53:42

Well of course not. No one said that they were. One has integral spin and the other has half-integral spin. Neutrinos are fermions, though. They have a spin of 1/2.

Quote from: esquire on 15/06/2019 17:53:42

That's plainly untrue. Bosons were known to be particles long before the Higgs boson was discovered.

Clueless to explain what?

Nobody said that bosons were fermions. You are creating a straw-man argument.

Quote from: esquire on 15/06/2019 17:53:42

Some bosons don't have a charge, like photons and gluons. Some do, such as the W+ and W- particles. Helium-4 nuclei are bosons as well, and they have a positive net charge due to their proton content. But neutrinos aren't bosons.

Bosons do interact via gravity. Remember gravitational lensing? Photons, which are bosons, are known to have their paths distorted by gravitational fields.

Quote from: esquire on 15/06/2019 17:53:42

The "contradiction" is all in your mind.

bosons belong in the quantum realm, they are zero mass, zero charge, with a twist(spin)  i.e. a photon. zero mass = not a particle.

The W+ and W- bosons actually have a very high rest mass and they also have electric charge. Also, photons don't have zero total mass. They have a mass equal to their energy content through the relationship E=mc2.

Quote from: esquire on 15/06/2019 17:53:42

Photons don't have a charge.

"Photons don't have a charge." 

van physics.illinois.edu/qa/listing.php?id=2348&t=photons-as-carriers-of-the-electromagnetic-force

"high-energy photons produced in particle accelerators may collide with themselves readily."

this insinuates a contradicts in regards to a charged photon.



me " is the warping of space/time a homogenous feature without imperfections, some academics, obviously think so!

kyptid
"I don't understand what this sentence means."

me - it's a reference to space time foam or bubbles or holes. many with your level or greater expertise favor this.




kyptid
"The "contradiction" is all in your mind."

yes,  they are they should be in yours.



kyptid
"Some bosons don't have a charge, like photons and gluons"  "Bosons do interact via gravity."

presenting both sides for a better possible understanding.

www quora.com/Does-a-moving-charged-particle-have-any-effect-on-gravitational-field
"So once again, the answer to your question is yes: any particle with mass is gravitationally attracted to any other particle with mass, regardless of whether these particles are charged or not."

physics stackexchange.com/questions/87874/why-does-the-standard-model-predict-neutrinos-are-massless

"However the experimentally established phenomenon of neutrino oscillation, which "mixes" neutrino flavour states with neutrino mass states (analogously to CKM mixing), requires neutrinos to have nonzero masses.

yet a neutrino which you claim to have gravitational mass is not attracted to an anti neutrino.  contradiction?

too wordy?
a foamed warped space/time fabric is essentially holes. fermion matter on the atomic level is essentially empty space. a neutrino is a bosonic empty field carrying a spin without mass, same as a bosonic photon. a higgs field only develops an energy signature after concussive event that forces one higgs field into another, an empty field in an empty field, wave in a wave. for the lack of a better analogy, a hole in a hole, creating a "well" negative potential. after the  higgs field develops an energy signature, it escapes with at least the speed of light, or does it utilize a foam spacetime to appear to do so?

Photons are carriers of the electromagnetic force, but they themselves do not have an electric charge. The reason that high-energy photons can sometimes interact with each other is because they can briefly transform into electron-positron pairs.

Nope, gotta stop you right there. Neutrinos are fermions by the very definition of what a fermion is: a particle with half-integral spin. Neutrinos have the exact same spin value as electrons and quarks (a spin of 1/2). They are firmly fermions.

the link below discusses this question and is obliquely ambiguous. I don't believe science is 100% certain as to the status of the neutrino*,  again I wish to thank you and evan-au for your time and input, it is much appreciated.

We know that the neutrino and antineutrino have to have a spin of 1/2 due to conservation of angular momentum. When a free neutron decays, it turns into a proton, an electron and an antineutrino. Since neutrons have a spin of 1/2, the total spin of all of the decay products must add up to either +1/2 or -1/2 (depending on the direction of the neutron's spin). The proton and electron both have a spin of 1/2 (which can also either be +1/2 or -1/2). If the proton and the electron have the same spin (either both +1/2 or both -1/2), then the antineutrino must be of the opposite spin sign and magnitude in order to make the total spin add up to the original neutron's spin. So the antineutrino must have a spin of 1/2. Since antineutrons decay into antiprotons, positrons and neutrinos, the same 1/2 spin must be possessed by the neutrino as well.
