Identified particle production as a function of multiplicity in proton-proton collisions at √s = 7 TeV using the ALICE detector

Usually, measurements of particle production in proton-proton collisions are carried out for understanding the particle production mechanisms in small systems and to provide a reference for the Pb-Pb results. Out of a number of observables, the transverse momentum (p_T) spectra and yields are fundamental tools to study the properties of the system created during the collisions. The p_T spectra of hadrons contain information about the collision dynamics and the entire space-time evolution from the initial to the final stage of the collision. On the other hand, yields are sensitive to the particle production mechanisms. Recent measurements of p_T spectra and baryon to meson ratios as a function of multiplicity in p-Pb collisions at √s = 5.02 TeV suggest a behaviour reminiscent of that observed in Pb-Pb collisions. The ratio of integrated yields for different particles w.r.t pions follow a universal trend across multiplicity from p-Pb to Pb-Pb collisions
