DOI: 10.1103/physrevd.102.054513
Abstract: We calculate the low-lying spectrum of charmed baryons in lattice QCD on the $32^3\times64$, $N_f=2+1$ PACS-CS gauge configurations at the almost physical pion mass of $\sim 156$ MeV/c$^2$. By employing a set of interpolating operators… read more here.

DOI: 10.1103/physrevd.104.034037
Abstract: We use QCD sum rules to study mass spectra of P -wave charmed baryons of the SU(3) flavor 6F . We also use light-cone sum rules to study their Sand D-wave decays into ground-state charmed… read more here.

DOI: 10.1103/physrevd.96.094005
Abstract: We have systematically studied the strong and radiative decays of the low-lying $1P$-wave doubly charmed baryons. Some interesting observations are: (i) The states $\Xi_{cc}^*$ and $\Omega_{cc}^*$ with $J^P=3/2^+$ have a fairly large decay rate into… read more here.

Abstract: Using the entire Belle data sample of 980 fb(-1) of e(+)e(-) collisions, we present the results of a study of excited Omega(c) charmed baryons in the decay mode (sic)(c)(+) K-. We show confirmation of four… read more here.

DOI: 10.1103/physrevd.98.091502
Abstract: The discovery of $\Xi_{cc}^{++}$ by the LHCb Collaboration triggers predictions of more doubly charmed baryons. By taking into account both the $P$-wave excitations between the two charm quarks and the scattering of light pseudoscalar mesons… read more here.

DOI: 10.1103/physrevd.98.113005
Abstract: The lifetimes of doubly charmed hadrons are analyzed within the framework of the heavy quark expansion (HQE). Lifetime differences arise from spectator effects such as $W$-exchange and Pauli interference. The $\Xi_{cc}^{++}$ baryon is longest-lived in… read more here.

DOI: 10.1134/s1063778818030134
Abstract: Abstractfinite size of a doubly heavy diquark yields a positive correction to baryon masses calculated in the local-diquark approximation. Upon evaluating this correction for the ground states of doubly charmed baryons, it became possible to… read more here.
