Measurements of hadron production in pPb collisions in CMS

Spectra of pions, kaons, and protons are measured in pPb collisions at $\sqrt{s_{NN}}=5.02$~TeV with the CMS detector at the LHC. The particle identification in the laboratory rapidity of $-1<y_{\rm lab}<1$ and transverse momentum of 0.1--1.7~GeV/{\it c} is performed using energies deposited i...

description Spectra of pions, kaons, and protons are measured in pPb collisions at $\sqrt{s_{NN}}=5.02$~TeV with the CMS detector at the LHC. The particle identification in the laboratory rapidity of $-1<y_{\rm lab}<1$ and transverse momentum of 0.1--1.7~GeV/{\it c} is performed using energies deposited in the silicon tracker. The average transverse momentum is found to increase with particle mass and charged multiplicity of the events. Comparisons to Monte Carlo event generators are performed. The EPOS LHC model, which incorporates additional hydrodynamic evolution of the created system, is able to reproduce most of the data features, unlike HIJING and AMPT. The measured transverse momentum spectra and integrated particle yields are also compared to those observed in pp and PbPb collisions in classes of charged multiplicity at various collision energies. The results indicate that particle production at LHC is strongly correlated with event multiplicity.
