Description
In this work the D-s2*(2573)+D+K-0 vertex is studied and the coupling constant corresponding to the D-s2*(2573)(+) -> (D+K0) transition is calculated. The calculation is performed using three point QCD sum rules method and the value of the coupling constant is obtained as gD(s2)*(DK) = (12.85 +/- 3.85) GeV-1. The coupling constant is also used to calculate the decay width and the branching ratio of the considered transition.
