Process gamma sup *gamma -> sigma at large virtuality of gamma sup *

The process gamma sup *gamma -> sigma is investigated in the framework of the SU(2) x SU(2) chiral Nambu-Jona-Lasinio model. The form factor of the process is derived for arbitrary virtuality of gamma sup * in the Euclidean kinematic domain. The asymptotic behaviour of this form factor resembles...

description The process gamma sup *gamma -> sigma is investigated in the framework of the SU(2) x SU(2) chiral Nambu-Jona-Lasinio model. The form factor of the process is derived for arbitrary virtuality of gamma sup * in the Euclidean kinematic domain. The asymptotic behaviour of this form factor resembles the asymptotic behaviour of the gamma sup *gamma -> pi form factor
