Abstract:

We present an extension to

\pi^{\pm} p

and

K^{\pm} p

elastic scattering at high energies of the impact-picture phenomenology we first proposed more than twenty years ago, for

p p

and

\bar p p

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

\pi p

and

K p

elastic scattering at high energies. It is proposed that

\pi^{\pm}

and

K^{\pm}

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

\bar p p

elastic scattering is updated by including new data and we give predictions for future experiments at BNL-RHIC and CERN-LHC.
