Query: Spectrum of Higher excitations of $B$ and $D$ mesons in the relativistic
  potential model   We study the masses and wave functions of heavy-light quark-antiquark system
in the relativistic potential model, where we focus on the higher excited
states of $B$ and $D$ mesons. The resonances of $D_J(2740)$, $D_J^*(2760)$,
$D_J^*(3000)$ and $D_{sJ}^*(2860)$ recently observed in experiments are
considered. We find that the four resonances can be identified as the
$|1^{1,3}D_2\rangle$, $|1^3D_3\rangle$, $|1^{1,3}F_3\rangle$ and
$|1^3D_3\rangle$ states due to the prediction to the states with $l=2$ and
$l=3$ in the potential-model calculation. The masses of $n=2$ excited states
are also calculated. All the observed mesons can be accommodated successfully
in the potential model.
