Axial-vector nucleon-to-delta transition form factors using the complex-mass renormalization scheme.

We determine the available six free parameters by fitting to an empirical parametrization of the form factors obtained from the BNL neutrino bubble chamber experiments. A unique feature of our calculation is the prediction of a nonvanishing form factor C-3(A)(Q(2)). Moreover, our results show a surprising sensitivity to the coupling constant g1 of the leading-order Lagrangian L-pi Delta((1)).eninfo:eu-repo/semantics/openAccessChiral Perturbation-TheorySingle-Pion ProductionCharged-CurrentNeutrinoExcitationDeuteriumEnergyElectroexcitationElectroproductionAmplitudesArticle1049094014-1094014-1410.1103/PhysRevD.104.094014Q1WOS:0007185881000042-s2.0-85119589278
