The charged particle transverse momentum (
) spectra measured by the ATLAS and CMS collaborations for proton–proton collisions at 
and 7 TeV have been studied using Tsallis thermodynamics. A thermodynamically consistent form of the Tsallis distribution is used for fitting the transverse momentum spectra at mid-rapidity. It is found that the fits based on the proposed distribution are working over 14 orders of magnitude with values up to 200 GeV/c and this gives a value of 
of 0.52/24 for the CMS data at 7 TeV. The values for 
as a function of center-of-mass energy obtained using a Tsallis distribution for both ATLAS and CMS data sets are presented and discussed.
