Multiplicity dependence of pion, kaon, and (anti)proton production at large transverse momentum in p--Pb collisions measured with ALICE at the LHC
Description
In this talk the measurement of the multiplicity dependence of
charged pion, kaon, and (anti)proton production in p-Pb collisions
at $\sqrt{s_{\rm NN}}\,=5.02$\,TeV at high transverse momenta (<20
GeV/$c$) will be shown, using the ALICE detector at the LHC.
The transverse momentum range of the measurement is extended with
respect to the already published low-pT results up to 20 GeV/$c$ in
seven multiplicity classes, using the capabilities of the High
Momentum Particle Identification Detector (HMPID) and the Time
Projection Chamber (TPC) in the relativistic rise regime.
The presented measurement includes the transverse momentum spectra
for $\pi^{\pm}$, K$^{\pm}$ and p($\bar{p}$), the ratios of spectra
among different particle species and the nuclear modification
factor ($R_{\rm pPb}$) in non-single diffractive p-Pb collisions.
The evolution of the spectral shapes and the particle ratios with
event multiplicities will be shown and their comparison with pp and
Pb-Pb results will be discussed.
