First CMS Heavy-Flavour results at 13 TeV
Measurements of b-hadron and quarkonium production cross sections provide essential information to understand QCD. This talk will show new measurements of double-differential production cross sections vs. transverse momentum pT and rapidity y at center-of-mass energy of 13 TeV performed by CMS experiment with data collected in 2015. Comparisons with results obtained at 7 TeV will be shown.
