Study of the inclusive production of charged pions, kaons, and protons in pp collisions at sqrt{s} = 0.9, 2.76,{ and }7 {TeV}
Abstract
Spectra of identified charged hadrons are measured in pp collisions at the LHC for sqrt{s} = 0.9, 2.76,{ and } 7 {TeV}. Charged pions, kaons, and protons in the transverse-momentum range p T≈0.1-1.7 GeV/ c and for rapidities | y|<1 are identified via their energy loss in the CMS silicon tracker. The average p T increases rapidly with the mass of the hadron and the event charged-particle multiplicity, independently of the center-of-mass energy. The fully corrected p T spectra and integrated yields are compared to various tunes of the Pythia 6 and Pythia 8 event generators.
