With the recent buzz about the Higgs boson, two questions arose to me:
1. What's the difference between it and 'graviton', described in wikipedia here: http://en.wikipedia.org/wiki/Graviton ?
2. Is the Higgs Boson matter or antimatter? Since (according to my limited knowledge) matching matter and anti-matter have the same mass, could it be that the Higgs Boson is actually a 'neutral' particle, in relation to that, or is there actually an anti- Higgs Boson that does the same for antimatter?
Thanks in advance for your reply!!!
The higgs boson has a mass of aprox 126.5 Ge/V^2.
How can the higgs boson have mass if it is the particle that gives things mass. Do higgs bosons always come in pairs so that they interact with each other to give each other mass?
And how do higgs bosons interact with massive objects? i.e., what particles do they exchange? Like two electrons exchange photons, doesn't a higgs particle and a massive object have to exchange some particles too? Do they exchange strings as in string theory?
Thank you very much for any replies :)
