Description

Many in te res t ing models based on the Regge-pole t h e o r y h a v e been p roposed to expla in t he elastic p r o t o n p r o t o n sca t t e r ing at h igh energies. Some of t h e m (1-3) are based on W u Y a n g ' s idea (4) w i t h a flat P o m e r o n , a n d o thers have used a more or less s loping P o m e r o n (5-7). Especia l ly the mode l p roposed by ABARBANEL et al. (s) is ve ry peculiar . Namely , in t he i r model t h e y have a s sumed the exis tence of two k inds of Pomerons in the sense t h a t b o t h cor respond to the s ingular i t ies which pass t h ro u g h J = 1 a t t = 0. One of the two P o m e r o n s is flat and cor responds to a po in t i n t e rac t ion of cur ren t cu r ren t form, and the o the r is s loping and cor responds to t he diff ract ion t e rm. The in te r fe rence t e r m was ignored in the i r p r e l im ina ry fits. All of these models have been e x a m i n e d in compar i son w i t h t he da t a a t p~ab~21 GeV/c (,.,1). However , r ecen t ly the slope of t he fo rward peak in t he range
