Asymptotic high-energy behavior of hadronic total cross sections from lattice QCD

Abstract

We will show how a universal and Froissart-like (i.e., of the kind "B log^2 s") hadron-hadron total cross section can emerge in QCD asymptotically at high energy, finding indications for this behavior from the lattice. The functional integral approach provides the natural setting for achieving this result, since it encodes the energy dependence of hadronic scattering amplitudes in a single elementary object, i.e., a proper correlation function of two Wilson loops.
