Abstract:

We report a measurement of the difference (ΔACP) between time-integrated CP-violating asymmetries in D0→K+K- and D0→π+π- decays reconstructed in the full data set of proton-antiproton collisions collected by the Collider Detector at Fermilab, corresponding to 9.7fb-1 of integrated luminosity. The strong decay D*+→D0π+ is used to identify the charm meson at production as D0 or D̄0. We measure ΔACP=[-0.62±0.21(stat)±0.10(syst)]%, which differs from zero by 2.7 Gaussian standard deviations. This result supports similar evidence for CP violation in charm-quark decays obtained in proton-proton collisions. © 2012 American Physical Society.

Abstract:

We present a search for the standard model Higgs boson produced in association with a W boson in √s=1.96TeV pp̄ collision data collected with the CDFA II detector at the Tevatron corresponding to an integrated luminosity of 9.45fb-1. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the W boson to an electron or muon and a neutrino, we set 95% credibility level upper limits on the WH production cross section times the H→bb̄ branching ratio as a function of Higgs boson mass. At a Higgs boson mass of 125GeV/c2, we observe (expect) a limit of 4.9 (2.8) times the standard model value. © 2012 American Physical Society.
