WebBethe-Salpeter (BS) equation with momentum dependent quark mass functions, determined by the Dyson-Schwinger (DS) equation, is able to explain successfully many spectroscopic data, such as meson masses [1–5], electromagnetic properties of pseudoscalar mesons and their radial excitations [6–9]) and other observables [10–21]. WebJul 14, 2024 · It has been known that the Dyson–Schwinger (DS) equations approach (see, e.g., Refs. [67, 68, 98,99,100,101]) is a continuous field theory of QCD, which can simultaneously deal with the confinement and dynamical chiral symmetry breaking, and is available on the entire \(T-\mu \) plane as well as zero current quark mass limit.

The Schwinger–Dyson equations (SDEs) or Dyson–Schwinger equations, named after Julian Schwinger and Freeman Dyson, are general relations between correlation functions in quantum field theories (QFTs).
