Identified particles in pPb collisions at $\sqrt{{s}_{NN}} =$ 5.02 TeV measured with the CMS detector

Spectra of identified charged hadrons in pPb collisions with the CMS detector at the LHC at $\sqrt{s_{NN}} =$ 5.02~TeV are presented. Charged pions, kaons,and protons in the transverse-momentum range $p_\mathrm{T} \approx$ 0.1--1.7 GeV/$c$ and laboratory rapidity $\vert y\vert < 1$ are identified...

description Spectra of identified charged hadrons in pPb collisions with the CMS detector at the LHC at $\sqrt{s_{NN}} =$ 5.02~TeV are presented. Charged pions, kaons,and protons in the transverse-momentum range $p_\mathrm{T} \approx$ 0.1--1.7 GeV/$c$ and laboratory rapidity $\vert y\vert < 1$ are identified via their energy loss in the silicon tracker. The average $p_\mathrm{T}$ increases with particle mass and the charged multiplicity of the event. The increase of the average $p_\mathrm{T}$ with charged multiplicity is greater for heavier hadrons. Comparisons to Monte Carlo event generators reveal that EPOS LHC, which incorporates additional hydrodynamic evolution of the created system, is able to reproduce most of the data features, unlike HIJING and AMPT. The average transverse momentum and particle ratio measurements indicate that particle production at LHC energies is strongly correlated with event particle multiplicity.
