Search for Low Mass Higgs at the Tevatron

Abstract

We present CDF and D0 searches for a Standard Model Higgs boson produced associatively with a W or Z boson at sqrt{s}=1.96 TeV using up to 1 fb^-1 of analyzed Tevatron data collected from February 2002 to February 2006. For Higgs masses less than 135 GeV/c^2, as is favored by experimental and theoretical constraints, WH->lnubb, ZH->llbb, and ZH->nunubb are the most sensitive decay channels to search for the Higgs boson. Both CDF and D0 have analyzed these three channels and found no evidence for Higgs production, and therefore set upper limits on the Higgs production cross-section. While the analyses are not yet sensitive to Standard Model Higgs production, improvements in analysis techniques are increasing sensitivity to the Higgs much faster than added luminosity alone.
