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.
