Abstract

We present a search for associated Higgs boson production in the process pp̅ → WH → WWW^*→ l^±νl′^±ν′ +X in final states containing two like-sign isolated electrons or muons (ℯ^±ℯ^±, ℯ^±μ^±, or μ^±μ^±). 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(pp̅→WH) × (Br(H→ WW^*) between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV.
