Abstract (English)

First principles Lattice quantum chromodynamics (LQCD) calculations enable the determination of low energy hadronic amplitudes. Precision LQCD calculations with relative errors smaller than approximately 1% require the inclusion of electromagnetic effects. We demonstrate that including (quenched) quantum electrodynamics effects in the LQCD calculation effects the values obtained for pseudoscalar ...

Translation of the abstract (German)

Gitter-QCD erlaubt die Bestimmung von hadronischen Amplituden bei niedriger Energie durch Simulation der fundamentalen Theorie. Präzissionsberechnungen mit relativen Fehler kleiner als ungefähr 1% machen es notwending elektromagnteische Effekte zu berücksichtigen. Wir demonstrieren dass Gitter QCD, erweitert um einen dynamische QED Hintergrund , es ermöglicht Permille Korrekturen zu ...
