Invariant-mass distribution of pK pairs after background subtraction for 0-10% multiplicity class in pp collisions at \sqrt{s} = 5.02 TeV
Detail description
Invariant-mass distribution for the Lambda(1520) in pp collisions at 5.02 TeV in the pT range 2.0 < pT < 2.5 GeV/c. 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 Lambda(1520)(solid blue curve) and the residual background (solid red curve).
