Soft and hard Pomerons in hadron elastic scattering at small
Physical Review D—Particles, Fields, Gravitation, and Cosmology, 2006•APS
We consider simple-pole descriptions of soft elastic scattering for pp, p¯ p, π±p and K±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 2≤ t≤-0.1 GeV 2, 6 GeV≤ s≤ 63 GeV. We
show that new form factors have to be used, and get information on the trajectories of the soft …
