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

Αγγλικά

We present a search for the standard model Higgs boson produced in
association with a W-+/- boson. This search uses data corresponding to
an integrated luminosity of 7.5 fb(-1) collected by the CDF detector at
the Tevatron. We select WH -> lvb (b) over bar candidate events with two
jets, large missing transverse energy, and exactly one charged lepton.
We further require that at least one jet be identified to originate from
a bottom quark. Discrimination between the signal and the large
background is achieved through the use of a Bayesian artificial neural
network. 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 (b)
over bar pairs, sigma(p (p) over bar -> (WH)-H-+/-) x B(H -> b (b) over
bar), relative to the rate predicted by the standard model. For the
Higgs boson mass range of 100 to 150 GeV/c(2) we set observed (expected)
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). The combination of the present search with an
independent analysis that selects events with three jets yields more
stringent limits ranging from 1.12 (1.79) to 34.4 (21.6) in the same
mass range. For 115 and 125 GeV/c(2) the upper limits are 2.65 (2.60)
and 4.36 (3.69), respectively.
