Photoproduction of Resonances from Compact and Spatially Extended Sources
Original language description
We discuss the photoproduction of resonances observed in the pi(+)pi(-) system. For the gamma p -> pi(+)pi(-) p reaction, we consider two production mechanisms: the one-pion exchange known in the literature as the Deck mechanism and collective contribution of all other short-range exchanges which we parametrize in terms of a smooth function of s(pi pi). We have found a very good agreement of the model with experimental mass distributions for partial waves S, P and D. Our calculations are in line with the expectation that while the P- and D-wave resonances rho(770) and f(2)(1270) are conventional q (q) over bar states, the S-wave f(0)(980) resonance is rather a more loosely bound qq (q) over bar(q) over bar state.
