The hard pomeron in soft data
arXiv:hep-ph/0310198 · doi:10.1016/j.physletb.2004.02.058
Abstract
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 pi p 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 pbar p data, provided one unitarises it at high energy.
