Soft and hard Pomerons in hadron elastic scattering at small t
Abstract
We consider simple-pole descriptions of soft elastic scattering for pp, pp, {pi}{sup {+-}}p and K{sup {+-}}p. We work at t and s small enough for rescatterings to be effectively absorbed in a simple-pole parametrization, and allow for the presence of a hard Pomeron. After building and discussing an exhaustive dataset, we show that simple poles provide an excellent description of the data in the region -0.5 GeV{sup 2}{<=}t{<=}-0.1 GeV{sup 2}, 6 GeV{<=}{radical}(s){<=}63 GeV. We show that new form factors have to be used, and get information on the trajectories of the soft and hard Pomerons.
