Abstract

We present a search for associated Higgs boson production in the process $p \bar{p} \to W / Z H \to ℓ^{\pm} ℓ^{' \pm} + X$ in $e e$ , $e μ$ , and $μ μ$ final states. The search is based on data collected by the D0 experiment at the Fermilab Tevatron Collider at $\sqrt{s} = 1.96 TeV$ corresponding to $5.3 {fb}^{- 1}$ of integrated luminosity. We require two isolated leptons (electrons or muons) with the same electric charge and additional kinematic requirements. No significant excess above background is observed, and we set 95% C.L. observed (expected) upper limits on ratio of the production cross section to the standard model prediction of 6.4 (7.3) for a Higgs boson mass of 165 GeV and 13.5 (19.8) for a mass of 115 GeV.
