Search for Associated Higgs Boson Production WH{yields}WWW*{yields}l{sup {+-}}{nu}l{sup '{+-}}{nu}{sup '}+X in pp Collisions at {radical}(s)=1.96 TeV

We present a search for associated Higgs boson production in the process pp{yields}WH{yields}WWW*{yields}l{sup {+-}}{nu}l{sup '{+-}}{nu}{sup '}+X in final states containing two like-sign isolated electrons or muons (e{sup {+-}}e{sup {+-}}, e{sup {+-}}{mu}{sup {+-}}, or {mu}{sup {+-}}{mu}{sup {+-}}). The search is based on D0 run II data samples corresponding to integrated luminosities of 360-380 pb{sup -1}. No excess is observed over the predicted standard model background. We set 95% C.L. upper limits on {sigma}(pp{yields}WH)xBr(H{yields}WW*) between 3.2 and 2.8 pb for Higgs boson masses from 115 to 175 GeV.
