N-Delta axial transition form factors
B. Golli, L. Amoreira, M. Fiolhais +1
We review some basic properties of the N-Delta transition axial amplitudes and relate them to the strong pi-N-Delta form-factor. In models with the pion cloud we derive a set of co…

Axial currents in electro-weak pion production at threshold and in the Delta-region
S. Sirca, L. Amoreira, M. Fiolhais +1
We discuss electro-magnetic and weak production of pions on nucleons and show how results of experiments and their interpretation in terms of chiral quark models with explicit meso…

Axial Excitation of the Delta in Chiral Quark Models
S. Sirca, L. Amoreira, M. Fiolhais +1
We discuss electro-magnetic and weak axial N-Delta transition amplitudes in the linear sigma-model and the Cloudy-Bag Model as typical representatives of chiral quark models. We sh…
