Measurement of the Bs0→J/ψKS0 branching fraction
R. Aaij, Carlos Abellán Beteta, B. Adeva, M. Adinolfi et autres
The Bs0→J/ψKS0 branching fraction is measured in a data sample corresponding to 0.41fb−1 of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2β measurement from B0→J/ψKS0. The time-integrated branching fraction …
