$B$ -jet fragmentation with $B^{\pm} \to J / I ¨ K^{\pm}$ decays in $s = 13$ TeV $pp$ collisions at LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1166

The collinear and transverse-momentum-dependent jet fragmentation function and the radial profile for $B^{\pm}$ mesons in jets are measured. The $B^{\pm}$ mesons are reconstructed…
