Production of K*(892)(0) and phi(1020) in p-Pb collisions at root s(NN)=5.02 TeV

Popis výsledku v původním jazyce

he production of K(892)(0) and phi(1020) mesons has been measured in p-Pb collisions at root s(NN) = 5.02 TeV. K*0 and phi are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range -0.5 < y < 0. The transverse momentum spectra, measured as a function of the multiplicity, have a p(T) range from 0 to 15 GeV/c for K*(0) and from 0.3 to 21 GeV/c for phi. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at root s = 7 TeV and Pb-Pb collisions at root s(NN) = 2.76 TeV. In Pb-Pb and p-Pb collisions, K*(0) and phi probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-phi ratio are discussed as a function of the multiplicity of the event. The short-lived K*(0) is measured to investigate re-scattering effects, believed to be related to the size of the system and to the lifetime of the hadronic phase.
