Pair production in differently polarized electric fields with frequency chirps
Obulkasim Olugh, Zi-Liang Li, Bai-Song Xie +1
Electron-positron pair production in strong electric fields, i.e., the Sauter-Schwinger effect, is studied using the real-time Dirac-Heisenberg-Wigner formalism. Hereby, the electr…
Bound state properties from the Functional Renormalisation Group
Reinhard Alkofer, Axel Maas, Walid Ahmed Mian +4
We discuss an approach for accessing bound state properties, like mass and decay width, of a theory within the functional renormalisation group approach. An important cornerstone i…
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…
On the low-energy spectrum of an SU(2) gauge theory with dynamical fermions
Milan Vujinovic, Reinhard Alkofer
The spectrum of light bound states in an SU(2) gauge theory with two flavors of fundamentally charged fermions is investigated by solving the Bethe-Salpeter equations in the respec…
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…
Decay mechanisms in bound state interaction kernels
A. S. Miramontes, H. Sanchis-Alepuz
We present progress on the study of decay-channel effects in the properties of hadrons using covariant Bethe-Salpeter equations (BSEs). The main goal will be to develop BSE kernels…
