Static-light meson spectroscopy with optimal distillation profiles
Laura Struckmeier, Roman Höllwieser, Francesco Knechtli +3
The spectrum of static-light and static-charm mesons is studied using optimized distillation in two different QCD ensembles with pion masses of $m_π \approx 80…
The strength of the interaction between quarks and gluons
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +4
Modern particle physics experiments, e.g. at the Large Hadron Collider (LHC) at CERN, crucially depend on the precise description of the scattering processes in terms of the known…
On the correlation coefficient T(E_e) of the neutron beta decay, caused by the correlation structure invariant under discrete P, C and T symmetries
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
We analyze the correlation coefficient T(E_e), which was introduced by Ebel and Feldman (Nucl. Phys. 4, 213 (1957)). The correlation coefficient T(E_e) is induced by the correlatio…
Non-perturbative renormalization by decoupling
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +3
We propose a new strategy for the determination of the QCD coupling. It relies on a coupling computed in QCD with degenerate heavy quarks at a low energy scale $…
Chiral Symmetry Breaking on the Lattice
Manfried Faber, Roman Höllwieser
We review important aspects of QCD in the continuum and on the lattice and take a look at the fate of its symmetries with an emphasis on chiral symmetry breaking on the lattice.
Comment on "Fractional topological charges and the lowest Dirac modes"
Derar Altarawneh, Roman Höllwieser
We comment on a recent article published in Phys. Rev. D98 (2018) no.9, 094513, arXiv:1811.09029, pointing out severe problems in the numerical investigation leading to questionabl…
