This shows a Feynman diagram for s-channel single top quark production. The top quark decays into a W boson and a b-jet. This week, a combined effort from the CDF and DZero experiments reported the observation of a new top quark process. This article discusses the contribution to that result from the CDF experiment. The top quark was discovered almost 20 years ago by the CDF and DZero experiments through a process in which it is produced in pairs. Events…

The best-fit cross section times branching ratio (σWH + σZH) x Br(H → bb) as a function of Higgs mass. The dark-shaded region shows the 68 percent confidence level interval; the light-shaded region shows the 95 percent confidence level region; and the Standard Model prediction is shown as the smooth, falling curve with a narrow band indicating the theoretical uncertainty. With the recent announcement of a new particle discovery by the LHC experiments, it seems very likely that the Higgs…
