Query: Study of the inclusive production of charged pions, kaons, and protons
  in pp collisions at sqrt(s) = 0.9, 2.76, and 7 TeV   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 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.
