Understanding the charmed states recently observed by the LHCb and BaBar Collaborations in the quark model

Abstract

Comparing the expected spectroscopy in the relativistic quark model and the predicted strong decays in the ${}^3{P}_0$ model employing the realistic wave functions from the relativistic quark model with the measured properties of the LHCb and BaBar charmed states, we find that the masses and strong decays of these charmed states can be reasonably explained in the conventional $q\bar{q}$ picture, and therefore suggest that the $D(2550)$/$D_J(2580)$, $D^{\ast }(2600)$/$D_J^{\ast }(2650)$, $D(2750)$/$D_J(2740)$, $D^{\ast }(2760)$/$D_J^{\ast }(2760)$, $D_J(3000)$, and $D_J^{\ast }(3000)$ can be identified as the $D(2^1{S}_0)$, $D(2^3{S}_1)$, $D_2^{\prime }(1D)$, $D(1^3{D}_3)$, $D(3^1{S}_0)$, and $D(1^3{F}_4)$, respectively.
