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…
and decay constants in QCD with Wilson fermions
Simon Kuberski, Fabian Joswig, Sara Collins +2
We present results for the leptonic decay constants of the D and D mesons from lattice QCD. We employ a set of 49 high statistics gauge ensembles generate…
Towards charm physics with stabilised Wilson fermions
Patrick Fritzsch, Jochen Heitger, Fabian Joswig +1
We report on a first study towards the use of stabilised Wilson fermions in heavy flavour physics. In particular, we are interested in fixing the charm quark mass via various physi…
Non-perturbative renormalisation and improvement of non-singlet tensor currents in QCD
L. Chimirri, P. Fritzsch, J. Heitger +4
Hadronic matrix elements involving tensor currents play an important rôle in decays that allow to probe the consistency of the Standard Model via precision lattice QCD calculations…
pyerrors: a python framework for error analysis of Monte Carlo data
Fabian Joswig, Simon Kuberski, Justus T. Kuhlmann +1
We present the pyerrors python package for statistical error analysis of Monte Carlo data. Linear error propagation using automatic differentiation in an object oriented framework…
Ratio of flavour non-singlet and singlet scalar density renormalisation parameters in QCD with Wilson quarks
Jochen Heitger, Fabian Joswig, Pia L. J. Petrak +1
We determine non-perturbatively the normalisation factor , where and are the renormalisation parameters of t…
Determination of the charm quark mass in lattice QCD with flavours on fine lattices
Jochen Heitger, Fabian Joswig, Simon Kuberski
We present a determination of the charm quark mass in lattice QCD with three active quark flavours. The calculation is based on PCAC masses extracted from flavou…

Jochen Heitger, Fabian Joswig
We present the results of a non-perturbative determination of the improvement coefficient and the renormalisation factor , which define the renormalise…
Ward identity determination of for lattice QCD in a Schrödinger functional setup
Jochen Heitger, Fabian Joswig, Anastassios Vladikas
We derive chiral Ward identities for lattice QCD with Wilson quarks and flavours, on small lattices with Schrödinger functional boundary conditions and vanish…
