Exchange of A1 and Z1 (jsup(P)sup(C) = 2--) mesons in charged pion photoproduction
Description
Finite energy sum rules are evaluated for the amplitudes corresponding to the exchange of the A1 and its exchange degenerate partner, the Z1(Jsup(P)sup(C) = 2--), in charged pion photoproduction. Both sum rules are roughly compatible with theoretical estimates of these exchanges, and a definite A1 signal found. (orig.)
