Investigation of the ensemble of maximal center gauge
Zeinab Dehghan, Rudolf Golubich, Roman Höllwieser +1
Maximal Center Gauge (MCG) aims to detect center vortices by maximizing a gauge functional and then projecting onto the center elements of the respective group. The requirement for…
Heavy Wilson Quarks and O() Improvement: Nonperturbative Results for
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +3
With Wilson quarks, on-shell O() improvement of the lattice QCD action is achieved by including the Sheikholeslami-Wohlert term and two further operators of mass dimension 5, wh…
Charmonium spectroscopy with optimal distillation profiles
Juan Andrés Urrea-Niño, Jacob Finkenrath, Roman Höllwieser +3
We use the method of optimal distillation profiles to compute the low-lying charmonium spectrum in an ensemble at the light flavor symmetric point ($m_π \approx…
Optimized Distillation Profiles for Heavy-Light Spectroscopy
Jan Neuendorf, Giulia Egbring, Jochen Heitger +4
It has been demonstrated that distillation profiles can be employed to build optimized quarkonium interpolators for spectroscopy calculations in lattice QCD. We test their usefulne…
A non-perturbative determination of
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +4
Close to the continuum limit, lattice QCD with mass-degenerate Wilson quarks can be described by Symanzik's effective continuum action, which contains the dimension 5 operator, $m\…
Spatial distribution of ultracold neutron probability density in the gravitational field of the earth above a mirror
Derar Altarawneh, Roman Höllwieser, Markus Wellenzohn
We propose a theoretical analysis of the experimental data by Ichikawa et al. (Phys. Rev. Lett. 112, 071101 (2014)) on a spatial distribution of ultracold neutrons in the gravitati…
