The spectra and particle yield ratios of π±, K± meson, protons and anti-protons in proton-proton (p − p) interactions at s=2.76$$ \sqrt{s}=2.76 $$ TeV are presented. CRMC generators: EPOS-LHC, EPOS1.99 and QGSJETII-04, are used for simulations and the results are compared with LHC-CMS experimental data. The particles are identified in the transverse momentum range of pT ≈ 0.1 − 1.7 GeV/c and absolute rapidity, ∣y∣ < 1. In simulation, same cuts in pT and y are used as in the experiment. The EPOS1.99 model predicts the data well as compared to the other two models, which predict in some of the pT regions only. The different models used could not effectively describe the experimental data in all pT range.
