dc.description.abstract | Using pp collisions corresponding to 4fb −1 integrated luminosity, recorded by the LHCb experiment at centre-of-mass energies of 13TeV, the ratio of branching fractions B(B c + → η c μ + ν μ )/B(B c → J/ψ μ ν μ )= (3.49 ± 0.86 stat. ± 0.20 syst. ± 0.34 PDG ) × 10 −1 , is determined, where the first uncertainty is statistical, the second systematic and the third come from the experimental measurement of the branching fractions η c → pp̄ and J/ψ → pp̄. There has been found evidence of the existence of the B c + → η c μ + ν μ decay at 3.7σ, including statistical and systematic uncertainties. (Texto tomado de la fuente) | eng |
