pp elastic scattering at LHC energies

Abstract

Using a unified analytic representation for the elastic scattering amplitudes of pp scattering valid for all energies above 20 GeV, the behavior of observables in the LHC collisions in the range $$\sqrt{s} =$$ 2.76–14 TeV is discussed. After the precise description of $$\mathrm{d}\sigma /\mathrm{d}t$$ at 7 TeV, we discuss the energy dependence of the amplitudes and expect that the proposed analytical forms give equally good predictions for the future experiments.
