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