Query: Interpretation of the newly observed $\Omega_c^0$ resonances   We study the charmed and bottomed doubly strange baryons within the
heavy-quark-light-diquark framework. The two strange quarks are assumed to lie
in $S$ wave and thus their total spin is 1. We calculate the mass spectra of
the $S$ and $P$ wave orbitally excited states and find the $\Omega_c^0 (2695)$
and $\Omega_c^0 (2770)$ fit well as the $S$ wave states of charmed doubly
strange baryons. The five newly $\Omega_c^0(X)$ resonances observed by the LHCb
Collaboration, i.e. $\Omega_c^0(3000)$, $\Omega_c^0(3050)$, $\Omega_c^0(3066)$,
$\Omega_c^0(3090)$, and $\Omega_c^0(3119)$, can be interpreted as the $P$ wave
orbitally excited states. In heavy quark effective theory, we analyze their
decays into the $\Xi^+_c K^-$ and $\Xi_c'^+ K^-$, and point out that decays of
the five P-wave $\Omega_c^0$ states into the $\Xi_c^+ K^-$ and $\Xi_c'^+K^-$
are suppressed by either heavy quark symmetry or phase space. The narrowness of
the five newly observed $\Omega_c^0(X)$ states can then be naturally
interpreted with heavy quark symmetry.
