Photoproduction of a0(980 ) and f0(980 )
Abstract
There is no generally accepted view of the structure of the light-quark nonstrange scalar mesons. A variety of models has been proposed that encompass q q q ¯q ¯ , molecular, q q ¯ , and glueball states in various combinations. Previously we considered scalar-meson photoproduction in a simple Regge-pole model and showed that it was experimentally viable. Recent data on the photoproduction of a0(980 ) and f0(980 ) confirm this. We extend our model to incorporate Regge cuts, based on our knowledge of π0 photoproduction. The theoretical predictions are compared to the a0(980 ) and f0(980 ) photoproduction data.
