Semileptonic and nonleptonic decays of $D$ into tensor mesons with light-cone sum rule

S. Momeni, R. Khosravi, S. Ghaziasgar

Form factors of $D$ decays into $J^{PC}=2^{++}$ tensor mesons are calculated in the light-cone sum rules approach up to twist-4 distribution amplitudes of the tensor meson. The mas…
