Measurement of the ratio B(t→Wb)/B(t→Wq) in pp collisions at √s=8 TeV
(2014-09-07)
The ratio of the top-quark branching fractions R = B(t → Wb)/B(t → Wq), where the denominator
includes the sum over all down-type quarks (q = b, s, d), is measured in the tt dilepton ¯ final state with
proton–proton ...
Observation of a peaking structure in the J/ψφ mass spectrum from B±→J/ψφK± decays
(2014-06-22)
A peaking structure in the J/ψφ mass spectrum near threshold is observed in B± → J/ψφK± decays,
produced in pp collisions at √s = 7 TeV collected with the CMS detector at the LHC. The data
sample, selected on the basis ...
