"Multiplicity dependence of charged pion, kaon, and (anti)proton production at
large transverse momentum in p-Pb collisions at 5.02 ATeV"
Dr. Gyula Bencedi, Wigner Institute, Hungary
The discovery of fluid-like behaviour in small collision systems (like pp,
pA) is one of the recent discoveries at the Large Hadron Collider (LHC). To
understand the origin of the phenomenon several observables are being
studied as a function of the event multiplicity. In particular, the
measurement of identified particle production in a broad transverse momentum
(pT) range provides valuable information since it is sensitive to flow-like
effects and new hadronization mechanisms like recombination and jet
quenching.
In this talk I am going to present the recent results [1] on the
multiplicity dependence of charged pion, kaon and (anti)proton production in
p-Pb collisions at 5.02 ATeV measured by the ALICE Collaboration at the LHC.
The detailed discussion of the analysis to measure the pT spectra will be
covered. Comparisons among pp, p-Pb and Pb-Pb collisions will be shown, in
addition the nuclear modification factor for identified particles in
non-single diffractive p--Pb collisions will be discussed as well.
