Pole-fitting for complex functions: enhancing standard techniques by artificial-neural-network classifiers and regressors
S. Kaidisch, T. U. Hilger, A. Krassnigg +1
Motivated by a use case in theoretical hadron physics, we revisit an application of a pole-sum fit to dressing functions of a confined quark propagator. More precisely, we investig…
Open-Flavour Mesons from the Angle of Bethe, Dyson, Salpeter, Schwinger, et al
Thomas Hilger, María Gómez-Rocha, Andreas Krassnigg +1
Recently, we completed a comprehensive investigation of a huge part of the entire meson spectrum by considering both quarkonia and open-flavour mesons by means of a single common f…
Global Dyson-Schwinger-Bethe-Salpeter Approach to Mesons with Open Flavour
Thomas Hilger, María Gómez-Rocha, Andreas Krassnigg +1
Exploiting an interplay of the Bethe-Salpeter equation enabling us to regard mesons as bound states of quark and antiquark and the Dyson-Schwinger equation controlling the dressed…
S- and D-wave vector charmonia
A. Krassnigg, T. Hilger
We revisit earlier calculations of leptonic decay constants of vector charmonia and present and illustrate our decomposition of the corresponding covariant Bethe-Salpeter amplitude…
Aspects of open-flavour mesons in a comprehensive DSBSE study
T. Hilger, M. Gómez-Rocha, A. Krassnigg +1
Open-flavour meson studies are the necessary completion to any comprehensive investigation of quarkonia. We extend recent studies of quarkonia in the Dyson-Schwinger-Bethe-Salpeter…
Charming quasi-exotic open-flavor mesons
Thomas Hilger, Andreas Krassnigg
We discuss charmed mesons in the covariant Dyson-Schwinger-Bethe-Salpeter-equation approach. In particular we computed masses, leptonic decay constants, and an orbital-angular-mome…
