Beyond rainbow-ladder calculations in the Dyuson-Schwinger and Bethe Salpeter approach
Abstract
The Dyson Schwinger (DSE) and Bethe-salpeter (BSE) formalism has shown great succes in describing hadron properties, such as ground state masses and space-like form factors. Nevertheless, typical truncations in the DSE/BSE system of equations, such as the Rainbow-Ladder truncation (RL), fails to correctly reproduce the spectrum of excited states and form factors in the time-like regime. We present results employing a Beyond rainbow-ladder truncation, which takes into account non-valence contributions in the DSE/BSE system and allows to obtain a better description of the hadronic structure.
