Description
Effects of nonresonant photoproductions arising from two different πNN couplings are investigated in the γN→ππN reaction. We find that the pseudoscalar (PS) πNN coupling is generally preferable to the pseudovector (PV) πNN coupling and particularly the total cross sections are successfully described by the model with the PS πNN coupling. In order to see the difference between the two couplings, we also show the results of invariant mass spectra and helicity-dependent cross sections in various isospin channels calculated with the PS and PV couplings
