We present an extension to and elastic scattering at high energies of the impact-picture phenomenology we first proposed more than twenty years ago, for p p and elastic scattering. We show, in particular, that the analytic form of the opacity function for the proton obtained previously is compatible with the experimental results on and K p elastic scattering at high energies. It is proposed that and external beams be provided from CERN-LHC, so that their elastic scattering from protons can be studied at higher energies. Our phenomenology for p p and elastic scattering is updated by including new data and we give predictions for future experiments at BNL-RHIC and CERN-LHC.
