Abstract
The transverse-momentum spectra of K and measured with the ALICE detector up to = 16 GeV/c in the rapidity range in p–Pb collisions at the center-of-mass energy per nucleon–nucleon collision TeV are presented as a function of charged particle multiplicity and rapidity. The measured distributions show a dependence on both multiplicity and rapidity at low whereas no significant dependence is observed at high . A rapidity dependence is observed in the -integrated yield (dN/dy), whereas the mean transverse momentum shows a flat behavior as a function of rapidity. The rapidity asymmetry ( ) at low (< 5 GeV/c) is more significant for higher multiplicity classes. At high , no significant rapidity asymmetry is observed in any of the multiplicity classes. Both K and show similar . The nuclear modification factor as a function of shows a Cronin-like enhancement at intermediate , which is more prominent at higher rapidities (Pb-going direction) and in higher multiplicity classes. At high (> 5 GeV/ ), the values are greater than unity and no significant rapidity dependence is observed.| File | Dimensione | Formato | |
