Decomposition of the axial-vector current in a finite box
Felix Hermsen, Matthias F. M. Lutz, Rob G. E. Timmermans
We consider the matrix element of the axial-vector current between two nucleon states in a finite box. Starting from the chiral Lagrangian density with nucleon and -isobar degre…

The axial-vector form factor of the nucleon in a finite box
Felix Hermsen, Tobias Isken, Matthias F. M. Lutz +1
We consider the axial-vector form factor of the nucleon in a finite box. Starting from the chiral Lagrangian with nucleon and Delta-isobar degrees of freedom, we address, at the on…

How much strangeness is needed for the axial-vector form factor of the nucleon?
Felix Hermsen, Tobias Isken, David Thoma +1
We consider the axial-vector together with its induced pseudo-scalar form factor of the nucleon as computed from the chiral Lagrangian with nucleon and isobar degrees of freedom. T…
