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…
QCD in the chiral SU(3) limit from baryon masses on Lattice QCD ensembles
Matthias F. M. Lutz, Yonggoo Heo, Renwick J. Hudspith
The baryon masses on CLS ensembles are used to determine the LEC that characterize QCD in the flavor-SU(3) limit with vanishing up, down, and strange quark masses. Here we reevalua…
Precise Omega baryons from lattice QCD
Renwick J. Hudspith, Matthias F. M. Lutz, Daniel Mohler
In this paper we determine the masses of and -baryon ground states using lattice QCD. We utilise Wilson-clover ensembles with…
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…
