Measurement of pion, kaon and proton production in proton–proton collisions at s√=7 TeV. Eur. Phys. J. C 75, 226 (2015). https://doi.org/10.1140/epjc/s10052-015-3422-91434-6044http://hdl.handle.net/10347/21527The measurement of primary π ±, K±, p and p production at mid-rapidity (|y| < 0.5) in proton–proton collisions at √ s = 7 TeV performed with a large ion collider experiment at the large hadron collider (LHC) is reported. Particle identification is performed using the specific ionisation energy-loss and time-of-flight information, the ringimaging Cherenkov technique and the kink-topology identification of weak decays of charged kaons. Transverse momentum spectra are measured from 0.1 up to 3 GeV/c for pions, from 0.2 up to 6 GeV/c for kaons and from 0.3 up to 6 GeV/c for protons. The measured spectra and particle ratios are compared with quantum chromodynamics-inspired models, tuned to reproduce also the earlier measurements performed at the LHC. Furthermore, the integrated particle yields and ratios as well as the average transverse momenta are compared with results at lower collision energieseng© CERN for the benefit of the ALICE collaboration 2015.
