    • نبذة مختصرة :
      The transverse-momentum (p(T)) spectra of K* (892)(0) and phi(1020) measured with the ALICE detector up to p(T) = 16 GeV/c in the rapidity range -1.2 < y < 0.3, in p-Pb collisions at the center-of-mass energy per nucleon-nucleon collision √sNN = 5.02 TeV are presented as a function of charged particle multiplicity and rapidity. The measured p(T) distributions show a dependence on both multiplicity and rapidity at low p(T) whereas no significant dependence is observed at high p(T). A rapidity dependence is observed in the p(T)-integrated yield (dN/dy), whereas the mean transverse momentum (< pT >) shows a flat behavior as a function of rapidity. The rapidity asymmetry (Y-asym) at low p(T) (< 5 GeV/c) is more significant for higher multiplicity classes. At high p(T), no significant rapidity asymmetry is observed in any of the multiplicity classes. Both K* (892)(0) and phi(1020) showsimilar Y-asym. The nuclear modification factor (QCP) as a function of p(T) shows a Cronin-like enhancement at intermediate p(T), which is more prominent at higher rapidities (Pb-going direction) and in higher multiplicity classes. At high p(T) (> 5 GeV/c), the Q(CP) values are greater than unity and no significant rapidity dependence is observed.
