Search for a Very Light <em>CP</em>-Odd Higgs Boson in Top Quark Decays from <em>pp</em> Collisions at √s=1.96  TeV

The contri- butions from standard model t t and dibosons are weighted as in Table I, while the contributions due to W jets and multijets are rescaled to account for the presence

We observe no significant excess over the expected background and thus set 95% confidence level upper limits on the Higgs boson production cross section for several Higgs boson

In the CDF II data sample of 2 : 2 fb 1 , we find no evidence of charged Higgs bosons in the dijet mass spectrum of the top quark decays. This analysis also yields conservative

After basic event selection, the total expected signal event yield in the current data set is 5:1 0:5 ( 3:5 0:4 ) single (double)-tag events for a Higgs boson with a mass of 115

Limits are placed on the production cross section and the branching fraction for the Higgs boson decay into a photon pair and compared to the predictions of a benchmark

To determine the observed (expected) exclusion contour in the stop-sneutrino mass plane, we set the number of events equal to the number of events in the data (total
