Axial and pseudoscalar form-factors of the Delta^+(1232)

Axial and pseudoscalar form-factors of the Delta^+(1232)

We present first results on the axial and pseudoscalar \(\Delta\) form factors. The analysis is carried out in the quenched approximation where statistical errors are small and the lattice set-up can be investigated relatively quickly. We also present an analysis with a hybrid action using staggered...

Zusammenfassung:We present first results on the axial and pseudoscalar \(\Delta\) form factors. The analysis is carried out in the quenched approximation where statistical errors are small and the lattice set-up can be investigated relatively quickly. We also present an analysis with a hybrid action using staggered sea quarks and domain-wall valence fermions.
