The region of soft collisions in nucleon-nucleon interactions occurs in the region of non-perturbative QCD. As such, there are numerous phenomological models present which attempt to describe various aspects of these collisions. The transverse momenta, distributions for charged particles at $\sqrt{s}=900$GeV, and $K$ and $\phi$ particles at $\sqrt{s}=7$TeV, for p-p collisions obtained from the ALICE experiment at the LHC were fitted using the Tsallis distribution using three parameters, namely T, q and R. The fits performed to these sets of data were found to be extremely satisfactory. However for Pb-Pb collisions the Tsallis distribution did not perform as well due to the neccesity to incorporate hydrodynamical considerations related to heavy-ion collisions, which are not incorporated in the distribution.
