Precise measurement of the fs/fd ratio of fragmentation fractions and of Bs0 decay branching fractions

The ratio of the B$^{0}_{s}$ and B0 fragmentation fractions, fs/fd, in proton-proton collisions at the LHC, is obtained as a function of B-meson transverse momentum and collision center-of-mass energy from the combined analysis of different B-decay channels measured by the LHCb experiment. The resul...
