Figure Caption

Invariant-mass distribution for the K*0 in pp collisions at 13 TeV in the pT range 1.2 < pT < 1.8 GeV/c and cos(theta*) bin 0.5-0.6. The figure shows the invariant-mass distribution after subtraction of the mixed-event background (plotted with statistical uncertainties) with a fit to describe the peak of the K*0 (blue solid curve) and the residual background (red dashed curve).
