Test of OPE and OGE through mixing angles of negative parity N* resonances in electromagnetic transitions
He Jun, Dong Yubing
Abstract
In this report, by using the mixing angles of one-gluon-exchange model(OGE) and one-pion-exchange model(OPE), and by using the electromagnetic Hamiltonian of Close and Li, we calculate the amplitudes of L=1 N* resonances for photoproduction and electroproduction. The results are compared to experimental data. It's found that the data support OGE, not OPE.
