Electromagnetic isoscalar ρπγ exchange current and the anomalous action Original Research Article

Using modern data, we first refit constants needed to complete an anomalous View the MathML source Lagrangian obtained within the approach of hidden local symmetries. Then we derive from this Lagrangian electromagnetic isoscalar ρπγ and View the MathML source exchange currents needed in calculations of the deuteron electromagnetic form factors at large momentum transfers.
