In the Standard Model of particle physics, the strength of the couplings of the b quark to the u and c quarks, |Vub| and |Vcb|, are governed by the coupling of the quarks to the Higgs boson. Using data ...

Evidence for the decay mode X(3872) →ψ(2S)γ in B+→X(3872)K+decays is found with a sig-nificance of 4.4 standard deviations. The analysis is based on a data sample of proton–proton collisions, corresponding ...

The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities ...
