Hunting for the Higgs at D - Zero

he standard model unifies the electromagnetic and weak interactions into a single framework that requires that the electroweak symmetry of the unified theory is broken at low energies. In the standard model, this is accomplished through the Higgs mechanism. Beyond generating the requisite symmetry breaking, this mechanism also produces a heavy spin 0 particle, the Higgs bo-son. Observation of the Higgs boson is a key test of the underlying assumptions in the standard model. I will discuss the search for the Higgs boson at the Tevatron, focusing on the D0 search for the ZH → ℓℓbb process as an example to illustrate
