Baryon femtoscopy in √SNN = 2.76 TeV Pb–Pb collisions at ALICE

We present femtoscopic results for proton and Λ correlation functions measured by ALICE in √SNN = 2.76 TeV Pb–Pb collisions. Femtoscopic radii are extracted from pp, p-bar p-bar , and p p-bar pairs. Comparisons of these radii with those from pion and kaon analyses reveal an approximate transverse mass scaling that is consistent with explanations of radial flow. Inelastic final state interactions are explored in baryon-antibaryon correlations functions to investigate their relationship with reduced proton yields at LHC energies
