Example lambda invariant mass peak for Identity Method analysis

Detail description

Example lambda->p*pi- invariant mass peak in Pb-Pb collisions at 5.02 TeV, used to illustrate the Identity Method procedure along with corresponding weights figure.  10-20% centrality, lambda pt 1.3-1.4 GeV/c, lambda |eta| < 0.5, LHC15o (AOD194).  Fit to the background, and interpolation under signal peak, is shown.
