Hadronic production of $D(2550)$, $D^{\ast }(2600)$, $D(2750)$, $D_1^{\ast }(2760)$ and $D_3^{\ast }(2760)$

Abstract

Hadronic decays of radially excited $2D$ $D(2^3{D}_1)$, $D(2^3{D}_3)$, $D(2D_2)$ and $D(2D_2^{\prime })$ have been studied in a ${}^3{P}_0$ model. All OZI-allowed decay channels of these $2D$ $D$ resonances have been given, and relevant decay widths have been calculated. $D(2550)$, $D^{\ast }(2600)$, $D(2750)$, $D_1^{\ast }(2760)$ and $D_3^{\ast }(2760)$ can be produced in hadronic decays of $D(2^3{D}_1)$, $D(2^3{D}_3)$, $D(2D_2)$ and $D(2D_2^{\prime })$. In different assignments, hadronic decay widths and some relevant ratios from the $2D$ $D$ resonances to $D(2550)$, $D^{\ast }(2600)$, $D(2750)$, $D_1^{\ast }(2760)$ or $D_3^{\ast }(2760)$ final states have been predicted, which may provide some more information to identify these resonances in forthcoming experiments.
