We investigate the relative $P$-wave excitations of the $D^{(*)}\bar D^{(*)}$ systems using the QCD sum rule method. By introducing a covariant derivative between two ground-state charmed meson fields, we construct color-singlet interpolating currents to describe the relative orbital excitation between the two meson cl...

Heavy quark effective theory (HQET) permits seven $P$-wave states in each of the $\Sigma_c$, $\Xi_c^\prime$, and $\Omega_c$ flavor-sextet sectors, yet the experimentally visible spectra differ strikingly among the three sectors. We show that strong decays, kinematic thresholds, and configuration mixing act as a dynamic...

We investigate the $P$-wave flavor-sextet charmed and bottom baryons within heavy quark effective theory. A key motivation is provided by the recent evidence for the $\Xi_c(2882)^0$, which completes a sequence of four narrow $\Xi_c$ structures together with the $\Xi_c(2923)^0$, $\Xi_c(2939)^0$, and $\Xi_c(2965)^0$. The...
