Do we understand elastic scattering up to LHC energies?    [PDF]

Jacques Soffer

The measurements of high energy \bar p p and pp elastic at ISR, SPS and Tevatron colliders have provided usefull informations on the behavior of the scattering amplitude. A large step in energy domain is accomplished with the LHC collider presently running, giving a unique opportunity to improve our knowledge on the asymptotic regime of the elastic scattering amplitude and to verify the validity of our theoretical approach, to describe the total cross section \sigma_{tot}(s), the total elastic cross section \sigma_{el}(s), the ratio of the real to imaginary parts of the forward amplitude \rho(s) and the differential cross section d\sigma (s,t)/dt.
