Precision renormalisation and improvement of lattice QCD with Wilson fermions
Patrick Fritzsch, Jochen Heitger, Simon Kuberski +2
We renormalise (and improve) the flavour non-singlet axial current, pseudo-scalar density, vector current and tensor current, as well as quark masses, in O(a) improved lattice QCD…

Heavy quark masses from step-scaling
Simon Kuberski, Alessandro Conigli, Patrick Fritzsch +6
We present a determination of the charm- and bottom-quark masses using the heavy-quark step-scaling strategy. Renormalization is performed in small volumes where relativistic botto…

improvement of the flavour singlet scalar density in a setup with Wilson fermions
Pia Leonie Jones Petrak, Jochen Heitger, Fabian Joswig
We report on our Ward identity determination of the improvement coefficient for the flavour singlet scalar density, namely , from three-flavour lattic…
