Baryon femtoscopy in heavy-ion collisions at ALICE

In this report, femtoscopic measurements with pp, (p) over bar(p) over bar, p (p) over bar, p (Lambda) over bar, (p) over bar Lambda and Lambda(Lambda) over bar pairs in Pb-Pb collisions at root s(NN)= 2.76 TeV registered by ALICE at the LHC are presented. Emission source sizes extracted from the correlation analysis with ( anti) protons grow with the event multiplicity, as expected. A method to extract the interaction potentials (e.g. for p (Lambda) over bar and (p) over bar Lambda pairs) based on femtoscopy analysis is discussed. The importance of taking into account the so-called residual correlations induced by pairs contaminated by secondary particles is emphasized for all analyses mentioned above.
