We present a search for associated Higgs boson production in the process pp̅WHWWW*l±νl±ν′ +X in final states containing two like-sign isolated electrons or muons (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(pp̅WH) × (Br(HWW*) between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV.
