Simulated Higgs event

Dernière mise à jour : lundi 19 janvier 2009, par Daniel Bloch

Simulation of the characteristic signature of a Higgs : the tracks and energy deposits it would make in the D0 detector.

The proton-antiproton collision produced a Higgs particle, which decayed to two b-quarks (seen in the detector as energy in the calorimeter, and indicated by the red arrows at 11 and 5 o’clock), together with a W boson, whose decay products are an electron (the green track at two o’clock) and a neutrino (inferred from an imbalance in overall momentum - the blue arrow at twelve o’clock). This kind of "associated production" of a W together with the Higgs is much easier to identify than the Higgs alone. Discovery of the Higgs will require the accumulation and study of hundreds of events like this one.
