Pomeron pole plus grey disk model: Real parts, inelastic cross sections and LHC data

Abstract: I propose a two component analytic formula F (s, t) = F (1) (s, t) + F (2) (s, t) for (ab → ab) + (ab → ab) scattering at energies ≥ 100GeV ,where s, t denote squares of c.m. energy and momentum transfer.It saturates the Froissart-Martin bound and obeys Auberson-Kinoshita-Martin (AKM) [1] [2] scaling. I choose ImF (1) (s, 0) + ImF (2) (s, 0) as given by Particle Data Group (PDG) fits [3],[4] to total cross sections, corresponding to simple and triple poles in angular momentum plane. The PDG formula is extended… Show more

“…In models with a two-component structure of the high energy elastic scattering amplitude, there are different interpretations of the first and second terms: the Pomeron and a non-Regge background [40], the dipole Pomeron and dipole Odderon [45], the soft Pomeron and hard Pomeron [46], Regge pole theory parameterization of both terms [43], the Pomeron pole plus the gray disk model [47]. We see that the nature of the two-component amplitude of high energy elastic scattering is an open question.…”
