Obtaining the strong coupling constants g_{J/ψD_s D_s} and g_{ϕD_s D_s} from QCD Sum Rules

M. E. Bracco, M. Chiapparini, B. Osório Rodrigues

The form factors and coupling constants of the meson vertices J/ψD_s D_s and ϕD_s D_s were calculated using three point correlation functions within the QCD Sum Rules formalism. We…
