Description
Using data collected by the CMS experiment at the LHC, we performed precise measurements of decay properties of hadrons containing a b quark. The lifetime is a fundamental property of particles and an important observable in heavy hadrons physics. We measured this quantity for various b-hadrons at the precision of the world average. These measurements will allow to test QCD inspired theoretical models. We have also measured the differential prompt production cross sections of J/ψ, ψ(2S), and Υ(nS) (n = 1, 2, 3) vector mesons in pp collisions at 13 TeV. These results will contribute to consolidate the underlying hypotheses of NRQCD and provide further input to constrain the theory parameters.
