Strong D*₂(2460)<SUP>0</SUP> → D<SUP>+</SUP>π<SUP>-</SUP> Transition in QCD

Abstract

This work presents the analysis of the transition D*(2)(2460)(0) > D+pi(-). 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 gD*(2) D pi = (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.
