The Higgs Boson is the subatomic particle that physicists theorize as the particle responsible for attributing mass. However, it has yet to be detected. Summer results from Fermilab, the LHC's US rival, suggest physicists could be hunting five particles, not one. The idea of multiple Higgs-like bosons is supported by results gathered by the DZero experiment at the Tevatron particle accelerator
"The DZero results showed much more significant "asymmetry" of matter and anti-matter - beyond what could be explained by the Standard Model.
Bogdan Dobrescu, Adam Martin and Patrick J Fox from Fermilab say this large asymmetry effect can be accounted for by the existence of multiple Higgs bosons."
