Higgs particles

  1. Jul 20, 2004 #1
    Are Higgs particles all the same mass?
    Does a proton have more Higgs particles associated with its rest mass
    than an electron has associated with its rest mass?
    And does the mass of all Higgs particles equal the total rest mass of
    the universe? Do Higgs particles have short lifetimes like other
    particles in the vacuum?

    In the framework of the standard model yes, and the best estimate to date comes from june 2004, and is about 117 Gev/c2

    "Scientists at the Department of Energy's Fermi National Accelerator Laboratory today (June 9) announced new results that change the best estimate of the mass of the postulated Higgs boson from approximately 96 GeV/c2 to 117 GeV/c2"

    All Higgs particles have the same mass as meteor pointed out. The reason then why the restmass of a proton is not equal to the mass of for example a massive vektorboson, is decided by the way they interact with the Higgs-particle when spontanous symmetry-breaking occurs. Havy particles were able to absorb more Higgs particles due to strong interactions.

    We must see the Higgs-field as a field that is omnipresent in our universe though. it makes sure that the groundstate is degenerate so that nature is able to select one groundstate out of multiple possibilities so that symmetrybreaking can occur. It is the same as the transition of a system to the superconducting fase in solid state fysics or as in the dual superconductor-models of quark-confinement. The higgs-particle here is merely the Cooperpairs which give rise to the special properties of a superconducting-medium, like zero-resitance due to the bosonic properties of Cooperpairs. The all want to sit together so it is very difficult to scatter Cooperpairs out of a Cooperpair-current.
