A new analysis of PP --> bblvjj at the LHC: Higgs and W boson associated production with two tag jets
Alessandro Ballestrero, Giuseppe Bevilacqua, Ezio Maina
Higgs production in association with a W boson and two energetic tag jets at the LHC is studied for MH=120 , with the Higgs decaying to bbˉ and the W
