Description

We present an update of a simple parametrization of the elastic differential cross-section,originally based on two exponential terms and a relative phase. Previous analyses of TOTEM data at LHC7 had shown the model to be able to reproduce well the region before, through and after the dip, however missing by 10-20 % the optical point. We show that inclusion of a multiplicative factor, corresponding to the proton form factor, can describe well the entire t-region measured by TOTEM. Application of two asymptotic Sum Rules, allows for predictions at higher LHC energies. Predictions from a QCD based model for inelastic and total cross-section will also be presented, with comparison with data from different LHC experiments.
