Toward heavy-light mesons from a Dyson-Schwinger-Bethe-Salpeter approach
Maria Gomez Rocha
Using a simple interaction model in the context of the Dyson-Schwinger-Bethe-Salpeter approach, quantitative corrections beyond the phenomenologically very useful rainbow-ladder truncation are presented for various heavy-light pseudoscalar and vector mesons. The effects of a dressed quark gluon vertex are in this way studied and discussed.
