The 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 identifi-
cation 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 energies.
