Abstract
We show that geometrical scaling exhibited by the spectra measured by the CMS collaboration at the LHC is substantially improved if the exponent of the saturation scale depends on . This dependence is shown to be the same as the dependence of small exponent of structure function in deep inelastic scattering taken at the scale
