The Position and the Residues of the Delta Resonance Pole in Pion Photoproduction

Abstract

We have analyzed the M (3=2) 1+ and E (3=2) 1+ multipole amplitudes of pion pho-toproduction in the framework of xed-t dispersion relations. Applying the speed plot technique to our results for these multipoles, we have determined the position and the residues of the (1232) resonance pole. The pole is found at total c:m: energy W = (1211?50i) MeV on the… (More)
