Abstract
We report on a search for the standard-model Higgs boson in pp-bar collisions at s**(1/2) =1.96 TeV using an integrated luminosity of 2.0 fb. We look for production of the Higgs boson decaying to a pair of bottom quarks in association with a vector boson V (W or Z) decaying to quarks, resulting in a four-jet final state. Two of the jets are required to have secondary vertices consistent with B-hadron decays. We set the first 95% confidence level upper limit on the VH production cross section with V -> qq-bar/qq')H(-> bb-bar) decay for Higgs boson masses of 100-150 GeV/c2, we exclude cross sections larger than 38 times the standard-model prediction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
