Search for $WH\to \ell \nu b\bar{b}$ Final States at the Tevatron

Abstract

Latest results are presented in the search for low mass standard model Higgs production in association with a $W$ boson, based on large luminosity data samples collected at the CDF and D0 Experiments at the Fermilab Tevatron $p\bar{p}$ collider. The selection of event samples containing an isolated lepton, an imbalance in transverse energy in the events, and either one or two reconstructed jets consistent with having evolved from a $b$-quark, provides statistically independent data samples to search for $q\bar{q}\to WH$ candidates. Expected and observed upper limits are derived for the product of the $WH$ production cross section and branching ratios and are reported in units of the standard model prediction. The observed (expected) upper limits for a Higgs mass $M_H=115\mathrm{GeV}$ are factors 2.65 (2.6) and 4.6 (3.5) above the standard model prediction for the CDF and D0 searches, respectively.
