The $D_{s}D{K}^{\ast }$ vertex in QCD Sum Rules: form factors and coupling constant

A. Cerqueira, B. Osório Rodrigues, M. E. Bracco +1

In this work we study the meson vertex $D_{s}D{K}^{\ast }$ using the QCD sum rules. We compute the three point correlation functions for the three cases of different off-shell mesons. The fo…
