Description

The identified and charged particle spectra have been measured in p - p and p - Pb collisions at LHC energies. A thermodynamically consistent form of the Tsallis distribution at y = 0 has been used for fitting the transverse momentum spectra $d^{2}N/d{p}_{T}dy$ and to evaluate the particle yields. The Tsallis distribution described the $p_T$ spectra very well. The values of $dN/dy{|}_{y=0}$ obtained from the Tsallis distribution are in agreement with the values measured by the LHC experiments. The centre-of-mass energy dependence of $dN/dy{|}_{y=0}$ and data to fit ratio will be presented and discussed.
