Abstract:	The ratio of the B 0 s and B + fragmentation fractions f s and f u is studied with B 0 s → J / ψ ϕ and B + → J / ψ K + decays using data collected by the LHCb experiment in proton-proton collisions at 7, 8, and 13 TeV center-of-mass energies. The analysis is performed in bins of B -meson momentum, longitudinal momentum, transverse momentum, pseudorapidity, and rapidity. The fragmentation-fraction ratio f s / f u is observed to depend on the B -meson transverse momentum with a significance of 6.0 σ . This dependency is driven by the 13 TeV sample ( 8.7 σ ), while the results for the other collision energies are not significant when considered separately. Furthermore, the results show a 4.8 σ evidence for an increase of f s / f u as a function of collision energy.
