The soft and the hard pomerons: elastic scattering and unitarisation
J. R. Cudell, A. Lengyel, E. Martynov +1
The hard pomeron component needed to reproduce small-x data seems to be present in elastic scattering at moderate energy. If this is the case, it is likely that the total cross sec…
Elastic Meson-Nucleon and Nucleon-Nucleon Scattering: Models vs. All Available Data
E. Martynov, J. R. Cudell, A. Lengyel
We consider simple-pole descriptions of soft elastic scattering at small and , and allow for the presence of a hard pomeron. We have built and analyzed an exhaustive dataset…
Hard pomeron contribution to forward elastic scattering
J. R. Cudell, A. Lengyel, E. Martynov +1
The introduction of a hard singularity in fits to total cross sections and to the ratio of real to imaginary parts enables to reproduce perfectly the data for sqrt(s)< 100 GeV usin…
Soft data and the hard pomeron
J. R. Cudell, A. Lengyel, E. Martynov +1
We show that the introduction of an additional, hard, singularity in soft forward amplitudes enables one to improve considerably the fits using a simple-pole structure for the soft…
