We present a search for associated Higgs boson production in the process ppbar à WH à WWW*à l± n l’± n’ in final states containing two like-sign isolated electrons or muons (e± e±, e± m±, or m± m±). 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 s(ppbar à WH) x Br(H à WW*) between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV.
