Hadronic physics from a Wilson fermion mixed-action approach: Setup and scale setting
Andrea Bussone, Alessandro Conigli, Julien Frison +6
We introduce a lattice QCD mixed action approach that employs Wilson-type quarks in the sea and valence sectors. The sea sector is based on gauge ensembles with fla…
Hadronic physics from a Wilson fermion mixed-action approach: Charm quark mass and meson decay constants
Andrea Bussone, Alessandro Conigli, Julien Frison +5
We present our first set of results for charm physics, using the mixed-action setup introduced in a companion paper. Maximally twisted Wilson valence fermions are used on a sea of…
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…
MOMO -- Deep Learning-driven classification of external DICOM studies for PACS archivation
Frederic Jonske, Maximilian Dederichs, Moon-Sung Kim +5
Patients regularly continue assessment or treatment in other facilities than they began them in, receiving their previous imaging studies as a CD-ROM and requiring clinical staff a…
Calculation of the running coupling in non-Abelian gauge theories from Jarzynski's equality
Olmo Francesconi, Marco Panero, David Preti
We discuss the theoretical foundations of non-equilibrium Monte Carlo simulations based on Jarzynski's equality and present, as an example of application, the determination of the…

We compute the running coupling of non-Abelian gauge theories in the Schrödinger-functional scheme, by means of non-equilibrium Monte Carlo simulations on the lattice.

We present a non-perturbative lattice study of SU(4) gauge theory with two flavors of fermions in the fundamental representation and two in the two-index antisymmetric representati…
