Abstract

The collinear and transverse-momentum-dependent jet fragmentation function and the radial profile for B± mesons in jets are measured. The B± mesons are reconstructed through the J/ψ (→ μ+ μ-) K± decay channel using proton-proton collision data collected during 2016-2018 with the LHCb detector at a center-of-mass (c.m.) energy of √s = 13 TeV, corresponding to an integrated luminosity of 5.4 fb-1. The results complement recent measurements of jet fragmentation functions for heavy-flavor hadrons and suggest a growing contribution of gluon fragmentation to B± mesons as the jet transverse momentum increases.
