The ratio of the $B^0_s$ and $B^0$ fragmentation fractions, $f_s/f_d$, in proton-proton collisions at LHC, is obtained as a function $B$-meson transverse momentum collision centre-of-mass energy from combined analysis different $B$-decay channels measured by LHCb experiment. results are described linear meson momentum, or with inspired Tsallis statistics. Precise measurements branching fractions $B^0_s \to J/\psi \phi$ D^-_s \pi^+$ decays performed, reducing their uncertainty about factor two respect to previous world averages. Numerous decay experiment, also updated using new values $f_s/f_d$ normalisation channels. These reduce major source systematic several searches for physics performed through fractions.
