In this work the D∗s2(2573)+D+K0 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∗s2DK (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.
