Electromagnetic isoscalar rho-pi-gamma exchange current and the anomalous action
E. Truhlik, J. Smejkal, F. C. Khanna
Abstract
Using modern data, we first refit constants needed to complete an anomalous pi-rho-omega-a1 Lagrangian obtained within the approach of hidden local symmetries. Then we derive from this Lagrangian electromagnetic isoscalar rho-pi-gamma and rho-a1-gamma currents needed in calculations of the deuteron electromagnetic form factors at large momentum transfers.
