Measurement of charged pion, kaon, and proton production in proton-proton collisions at √s = 13 TeV


Transverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at √s=13  TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon tracker, are measured in the transverse momentum range of p_T ≈ 0.1–1.7  GeV/c and rapidities |y| < 1. The pT spectra and integrated yields are compared to previous results at smaller √s and to predictions of Monte Carlo event generators. The average p_T increases with particle mass and charged particle multiplicity of the event. Comparisons with previous CMS results at √s = 0.9, 2.76, and 7 TeV show that the average p_T and the ratios of hadron yields feature very similar dependences on the particle multiplicity in the event, independently of the center-of-mass energy of the pp collision.
