Charged pions, kaons, and protons in the transverse-momentum range pt approximately 0.1-1.7 GeV and for rapidities abs(y) < 1 are identified via their energy loss in the CMS silicon tracker. The average pt increases rapidly with the mass of the hadron and the event charged-particle multiplicity, independently of the center-of-mass energy. The fully corrected pt spectra and integrated yields are compared to various tunes of the PYTHIA6 and PYTHIA8 event generators.engStudy of the inclusive production of charged pions, kaons, and protons in $pp$ collisions at $\sqrt{s}=0.9$, 2.76, and 7 TeVjournal article2019-02-03
