dc.description.abstractThe dependence of the ratio between the B-s(0) and B+ hadron production fractions, f(s)/f(u), on the transverse momentum (p(T)) and rapidity of the B mesons is studied using the decay channels B-s(0) -> J/psi phi and B+ -> J/psi K+. The analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment in 2018 and corresponding to an integrated luminosity of 61.6 fb(-1). The f(s)/f(u) ratio is observed to depend on the B p(T) and to be consistent with becoming asymptotically constant at large p(T). No rapidity dependence is observed. The ratio of the B-0 to B+ meson production fractions, f(d)/f(u), is also measured, for the first time in proton-proton collisions, using the B-0 -> J/psi K*(0) decay channel. The result is found to be within 1 standard deviation of unity and independent of p(T) and rapidity, as expected from isospin invariance.en_US
