Search for the standard model Higgs boson produced in association with a W boson with 7.5??fb-1 integrated luminosity at CDF

Popis výsledku v původním jazyce

We present a search for the SM Higgs boson produced in association with a $W^{/pm}$. This search uses data corresponding to an luminosity of 7.5 fb$^{-1}$ collected by the CDF. The number of tagged events and their distributions are consistent with the standard model expectations. We observe no evidence for a Higgs boson signal and set 95% C.L. upper limits on the $WH$ production cross section times the branching ratio to decay to $b/bar b$ pairs, $/sigma(p/bar p /rightarrow W^{/pm} H) /times {/cal B}(H/rightarrow b/bar b)$, relative to the rate predicted by the standard model. For the Higgs boson mass range of 100 GeV/c$^2$ to 150 GeV/c$^2$ we set observed upper limits from 1.34 (1.83) to 38.8 (23.4). For 115 GeV/c$^2$ the upper limit is 3.64 (2.78).Combination of the present search with an independent analysis that selects events with three jets yields more stringent limits from 1.12 (1.79) to 34.4 (21.6) in the same mass range. For 115 GeV/c$^2$ the upper limit is 2.65 (2.60).
