QCD Sum Rule Approach to the New Mesons and the gDsJDK Coupling Constant
We use diquark-antidiquark currents to investigate the masses and partial decay widths of the recently observedmesons D+sJ(2317), D¤00 (2308) and X(3872), considered as four-quark states, in a QCD sum rule approach.In particular we investigate the coupling constant gDsJDK. We found that the gDsJDK o...
