What does the following mean (from a list of B⁺ decay modes):

[K^-pi⁺]_DK⁺?

It may help if you include a reference.

Isn't the fundamental problem with Particle Physics, this.

No-one knows whether Particles actually exist, as discrete  physical " objects"

Or whether all so-called Particles, are only illusory manifestations.  Caused by regular fluctuations in what is really a continuous spectrum of Energy.

In something like, the way we could we look at the sea.  The sea is a continuous area, or "spectrum" of Water. Which is usually flat.

But sometimes this water is made to "fluctuate" and produce "Waves"

These "Waves" look physical different. In the sense that the Waves are tall, whereas the sea-water is flat.

But could anyone suggest that the "Waves" are a discrete and fundamentally different thing from sea-water?

If you can measure the mass and charge of a something, and it is different from something else, it is normal to assume that it exists as a discrete object. You might consider a brick to be a fluctuation in the continuum of elvish gossamer, but you could be detained for your own safety if you tried to convince anyone else.

You might consider a brick to be a fluctuation in the continuum of elvish gossamer, but you could be detained for your own safety if you tried to convince anyone else.

The thing about a brick, though, is that you can pick it up in your hand. Look at it. See the varying colours in its surface.  Then juggle it in your hand, to gauge its weight. Run your fingers across it, to sense the texture and corrugations in its surface..  Smell it, and even, if you so desire, lick it.

All this provides a wealth of evidence. To  convince you that the brick is a real, solid object. 

But, by contrast, suppose you go to particle physics.  And contemplate the supposed "Higg's Boson"
This is supposed to be as real as a brick.

Yet, didn't the HB's "discovery " rely entirely on the statistical analysis of numerical meter-readings..  Not even from any physical traces caused by its transit through a Bubble Chamber.

Doesn't that seem a bit, to say the least, shaky?

Yes, a brick lasts longer than a Muon (or a person).
- A human body will typically decay in a decade or so (in a temperate climate).
- Give the brick a million years of erosion by water, wind and sand, and the brick will decay to clay.

The fact of entropy and decay does not make the brick (or the person, or the Muon) any less real

If you accelerate the Muon up to almost the speed of light, you can preserve them a lot longer (due to time dilation), so you can study them more easily...

Thanks Evan.  You make interesting points. I don't believe the Higg's Boson actually exists though! Do you?

What I find "shaky" is the supposal that one who is not a particle physicist has a better understanding of particle physics than actual particle physicists do. Those experiments are carefully designed based on the known behavior of particles and the predicted behavior of the particles they are trying to detect. Those results are then reviewed by other scientists who also understand those things. Multiple tests and investigations are done to rule out system malfunctions or noise. This ain't just a guess on the part of physicists. They know what they are doing (and you can too, if you study it enough).

I don't believe the Higg's Boson actually exists though!

I think Neil deGrasse Tyson has a quote for that.

How are we meant to distinguish that from trolling?

Then you would be making a massive underestimate,..

Was Galileo trolling, when he dared propose that the prized epicycles required by 17th-century geocentric astronomy, didn't actually exist

The Pope seems to have thought so, and got Galileo banged up under house-arrest for life.

That couldn't happen today.  Or, could it?  Are there Popes on here?

[Bored chemist]

Was Galileo trolling,

No, he had evidence.

  Are there Popes on here?

Are you saying you really don't know the difference between science and religion, or are you trolling?

The search for the Higgs Boson is similar to the discovery of Neptune.
There were some discrepancies in the orbits of the outer planets that if correct would throw into question Newton’s laws of gravitation. An astronomer calculated that it could be explained by another planet and calculated where it should be. Observatories looked at that location and confirmed it was there.

You remind me of the people who would not believe in bacteria or viruses, because they couldn’t see them.

I suppose you don’t believe tornadoes are real either; after all, they are only fluctuations of the air so they can’t be ‘real’ can they.

I suggest as well that you learn something about bubble chambers. You keep quoting them but obviously don’t know how they work. If you did you would realise why it is ridiculous to keep quoting them.

Are there Popes on here?

Yes, you are one.
The Pope was trolling Galileo.

If you have comparable evidence on par with that of Galileo that the Higgs boson doesn't exist, please post it. Arguments from incredulity don't count.

Hello Charles!

Previously i thought your posts were  quite bent towards antiscientific promulgation and also evoked potential seeding of conspiracy theories.
(Perhaps, i still Think the same)
🤔

But Now...as i see the aftereffects of the Quality of content(information) your Words/Statements/Doubts bring out or receive in Response... I'm quite Pleased!
😇

Gotta say, very helpful towards a layperson who might have similar doubts but might not have the courage to speak up or speak out.
👍

I feel by constantly suspecting & doubting Scientific Methodologies, works out in directly proportional manners, thereby making it Alot more Stronger & Alot more Credible.
👌




P.S. - Please, keep up the Good Work!

Dear Chas, may I call you Chas? Well, anyway, you are made up of particles. Do you exist? Maybe you are just an illusory fluctuation. In which case, you can easily be ignored.
