Abstract

We present a search for associated Higgs boson production in the process

p \bar{p} \to W H \to W W W^{*} \to l^{\pm} ν l^{' \pm} ν^{'} + X

in final states containing two like-sign isolated electrons or muons (

e^{\pm} e^{\pm}

,

e^{\pm} μ^{\pm}

, or

μ^{\pm} μ^{\pm}

). The search is based on D0 run II data samples corresponding to integrated luminosities of

360 - 380 {pb}^{- 1}

. No excess is observed over the predicted standard model background. We set 95% C.L. upper limits on

σ (p \bar{p} \to W H) \times Br (H \to W W^{*})

between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV.
