Description
We parametrize the TOTEM data for the elastic differential pp cross section at 7 TeV in terms of two exponentials with a relative phase. We employ two previously derived sum rules for pp elastic scattering amplitude in impact parameter space to check whether asymptotia in hadron-hadron scattering has been reached at the LHC. A detailed study of the TOTEM data is made and it is shown that, within errors, the asymptotic sum rules are satisfied at LHC. We propose to use this parametrization to study forthcoming higher energy data.
