Search for the SM $ZH\to\mu\mu b\bar{b}$ production at D0
ORAL
Abstract
We present a search for the low mass standard model Higgs boson produced in association with a $Z$ boson, using 9.7~fb$^{-1}$ of data collected by the D0 detector at $\sqrt{s} = 1.96$~TeV. Events are selected to have a $Z$ candidate reconstructed either with two muons or one muon plus an isolated track, and at least two reconstructed jets with one or two jets satisfying the b-tagging requirements. A discriminant variable based on multivariate analysis technique is used to separate the Higgs signal and backgrounds. Upper limits on the $ZH$ production cross section times branching ratio are set at 95\% C.L. for the Higgs mass from 90 GeV to 150 GeV.
