Abstract
In the previous paper we have argued that the LHC data on multiplicity, average transverse momentum, and charged particle transverse momentum distributions are well described with minimal modeling in terms of a saturation scale Q_sat(s). As a consequence, the p_T spectra should exhibit geometric scaling. In this short note we show that recently released CMS data at sqrt{s}=0.9, 2.36 and 7 TeV fall on a universal curve when plotted in terms of suitably defined scaling variable \tau.
