Abstract :
[en] We show that the data for the total cross section and for the real part of the elastic amplitude indicate the presence of a hard pomeron in pip and Kp elastic scattering at t = 0, compatible with that observed in deep inelastic scattering. We show that such a hard pomeron is also compatible with pp and pp data, provided one unitarises it at high energy. (C) 2004 Published by Elsevier B.V.
