N Delta - Transition Form Factors at Low Momentum Transfer
G. C. Gellas, T. R. Hemmert, C. N. Ktorides, G. I. Poulis
Abstract
The three complex form factors entering the Δ Nγ vertex are calculated to O(ε3) in the framework of a chiral effective theory with explicit Δ(1232) degrees of freedom. Furthermore, the role of presently unknown low energy constants that affect the values of EMR and CMR is elucidated.
