“…Associated production cross section is 0.2-0.5 pb in the low mass range, but the presence of an extra vector boson from the Higgs associated production helps to reduce backgrounds. Therefore, H → bb searches at Tevatron exploit the associated production of the Higgs boson, with the W [42,43] or Z [44,45,46,47] boson decaying leptonically to increase the expected signal to background ratio. The three main final state, lνbb, ννbb and l + l − bb exhibit distinctive signatures: energetic leptons and/or undetected energy due to ν's.…”
