The $Xi_c^+ K^-$ mass spectrum is studied with a sample of $pp$ collision data corresponding to an integrated luminosity of 3.3 fb$^{-1}$, collected by the LHCb experiment. The $Xi_c^+$ is reconstructed in the decay mode $p K^- pi^+$. Five new, narrow excited $Omega_c^0$ states are observed: the $Omega_c(3000)^0$, $Omega_c(3050)^0$, $Omega_c(3066)^0$, $Omega_c(3090)^0$, and $Omega_c(3119)^0$. Measurements of their masses and widths are reported.
The $Lambda_c^+K^-$ mass spectrum is studied with a data sample of $pp$ collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 5.6 fb$^{-1}$ collected by the LHCb experiment. Three $Xi_c^0$ states are observed wi
The first observation of the $Omega_b^-toXi_c^+ K^- pi^-$ decay is reported using proton-proton collision data at centre-of-mass energies of $7$, $8$ and $13,mathrm{TeV}$ collected by the LHCb experiment, corresponding to an integrated luminosity of
Using a data sample of 980 ${rm fb}^{-1}$ of $e^+e^-$ annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy $e^+e^-$ collider, we report the results of a study of excited $Xi_c$ states that decay, via the emission of
Using 13.7 fb^{-1} of data recorded by the CLEO detector at CESR, we report preliminary evidence for two new charmed baryons; one decaying into Xi_c^{0prime} pi^+ with the subsequent decay Xi_c^{0prime} to Xi_c^0 gamma, and its isospin partner decayi
We study the weak decay $Omega_b^- to (Xi_c^+ , K^-) , pi^-$, in view of the narrow $Omega_c$ states recently measured by the LHCb collaboration and later confirmed by the Belle collaboration. The $Omega_c(3050)$ and $Omega_c(3090)$ are described as
