Title: Does the Higgs Boson have an antiparticle?
Post by: Physics Dilettante on 18/11/2008 15:41:26

If the Higgs boson exists, should it have an antiparticle? If so, would the antiparticle impart negative mass? And how might negative mass manifest itself?

Photons and gravitons are their own antiparticles  it is quite likely that the higgs particle (if it exists) comes into this category

Ok. So, the Higgs is hoped to be the graviton we've been looking for(?) And, while it imparts mass, it has no mass itself?

No! I never said that the higgs particle is a graviton.  A graviton is like a photon and mediates all gravitational interactions in quantum gravity. There are probably zillions of them about but they are such a low energy and frequency they are totally undetectable except in the way gravitational interactions take place.

Sorry for my misinterpretation.

I've since found the "Higgs Bosons vs Gravitons" thread (don't know why I didn't find it when I searched before posting), which explains things even further.

Thanks!
