Contribution

First measurement of B+ hadron differential cross sections at 13 TeV using the CMS detector with a new decay channel analysis.

Findings

Results agree with theoretical calculations within uncertainties

Differential cross sections as functions of pT and rapidity are provided

Data collected corresponds to 49.4 pb^-1 of integrated luminosity

Abstract

The differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pT[B] and rapidity y[B] in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 inverse picobarns. The measurement uses the exclusive decay channel B+ to J/psi K+, with J/psi mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.
