This work presents the analysis of the transition D2*(2460)0 → D+π−. In the calculation three point QCD sum rules method is applied and the value of the coupling constant for the considered vertex is obtained as gD2*Dπ = (12.72±3.56) GeV−1.The result of the calculation is also utilized in the decay width and branching ratio calculations of the considered transition.
