Figure Caption

Invariant-mass distributions $\Delta M$ for the charm-enhanced (left panel) and the beauty-enhanced (right panel) samples in pp collisions at $\s=13~\TeV$, selected with the high-multiplicity trigger. The distributions are obtained at midrapidity ($|y|<0.8$) in $5<\pt<7~\GeV/c$ and $0.0<\cost<0.2$.
