Query: Measurement of charged pion, kaon, and proton production in
  proton-proton collisions at sqrt(s) = 13 TeV   Transverse momentum spectra of charged pions, kaons, and protons are measured
in proton-proton collisions at sqrt(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 pt ~ 0.1-1.7 GeV and
rapidities abs(y) < 1. The pt spectra and integrated yields are compared to
previous results at smaller sqrt(s) and to predictions of Monte Carlo event
generators. The average pt increases with particle mass and charged particle
multiplicity of the event. Comparisons with previous CMS results at sqrt(s) =
0.9, 2.76, and 7 TeV show that the average pt 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.
