Spectra of identified charged hadrons are measured in pp collisions at the LHC for root s = 0.9, 2.76, and 7 TeV. Charged pions, kaons, and protons in the transverse-momentum range p(T) approximate to 0.1-1.7 GeV/c and for rapidities vertical bar y vertical bar < 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.
