The N to \(\Delta\) axial transition form factors in quenched and unquenched QCD

The four N to \(\Delta\) axial transition form factors are evaluated using quenched QCD, using two flavors of dynamical Wilson fermions and using domain wall valence fermions on three-flavor MILC configurations for pion masses down to 360 MeV. We provide a prediction for the parity violating asymmet...

Zusammenfassung:The four N to \(\Delta\) axial transition form factors are evaluated using quenched QCD, using two flavors of dynamical Wilson fermions and using domain wall valence fermions on three-flavor MILC configurations for pion masses down to 360 MeV. We provide a prediction for the parity violating asymmetry as a function of \(Q^2\) and examine the validity of the non-diagonal Goldberger-Treiman relation.
