Hadron properties from QCD bound-state equations: A status report
Reinhard Alkofer, Gernot Eichmann, Andreas Krassnigg +1
Employing an approach based on the Green functions of Landau-gauge QCD, some selected results from a calculation of meson and baryon properties are presented. A rainbow-ladder trun…
Nucleon mass from a covariant three-quark Faddeev equation
G. Eichmann, R. Alkofer, A. Krassnigg +1
We report the first study of the nucleon where the full Poincare-covariant structure of the three-quark amplitude is implemented in the Faddeev equation. We employ an interaction k…
Quantum statistics effect in Schwinger pair production in short laser pulses
Florian Hebenstreit, Reinhard Alkofer, Gerald V. Dunne +1
We investigate non-perturbative pair production from vacuum (the Schwinger effect) in the focal region of two counter-propagating, ultra-short laser pulses with sub-cycle structure…
Confinement & Chiral Symmetry Breaking: The fundamental problems of hadron physics
Reinhard Alkofer
Some of the difficulties arising when one tries to understand confinement as well as dynamical and anomalous chiral symmetry breaking are reviewed. Criteria to be fulfilled by a su…
Momentum signatures for Schwinger pair production in short laser pulses with a sub-cycle structure
Florian Hebenstreit, Reinhard Alkofer, Gerald V. Dunne +1
We investigate electron-positron pair production from vacuum for short laser pulses with sub-cycle structure, in the nonperturbative regime (Schwinger pair production). We use the…
