This weeks greatest news is the discovery of higgs boson like particle. My question is where higgs boson is found; whether it is found in both matter and antimatter or it is found only in matter, if only in matter then there is any theoretical anti higgs boson like particle present in antimatter or not?
This 125 GeV new particle is a neutral boson.Elementary neutral bosons are their own antiparticle, like the photon, the Z0 and now the Higgs. Composite ones may be so too, depending on the quantum numbers that the quarks they are composed of carry. The pi0 for example is its own antiparticle, since quark-antiquark switch roles.
where we can find higgs boson particle
Evidently, at the LHC. :)
The Higgs boson, as conceived in the Standard Model, is the observable quantum of 1 of the 4 degrees of freedom of the Higgs field. Loosely speaking, the anti-particle of the Higgs is "eaten" by the Z boson and so is not observable (except as the mass of the Z).
Higgs Boson is found everywhere in the universe (even where there is no matter). Its messenger particle of universe-wide Higgs field.
What is Messenger Particle?
Photon is messenger particle of electromagnetic field which defines the field (conditions of space). Higher field intensity means high density of photons. Similarly, gravitons are messenger particles of gravitational field. You can understand it as conveyor of gravitational force. Force/energy is exchanged with messenger particles.
Charge is determined by level of interaction with electromagnetic field. Similary, rest mass is determined by level of interaction with Higgs field. So, Higgs Boson gives something "Rest Mass" based on level of interaction with it. For example, photons don't interact with Higgs Boson at all, so photons don't have mass. Up Quarks interacts with it upto high extent, so they have high rest mass.
