Charmed baryons in a quark-diquark model
TLDR
In this paper, a quark-diquark model of baryons is generalized to include charmed baryon within the framework of the broken-symmetry groupsSU8 andSU8 ×O3.Abstract:
A quark-diquark model of baryons is generalized to include charmed baryons within the framework of the broken-symmetry groupsSU8 andSU8 ×O3. Mass relations are obtained for the baryons belonging to the lowest-lying level ofSU8, and some qualitative features of the higher levels are given.read more

Decay properties of $P$-wave charmed baryons from light-cone QCD sum rules
TL;DR: In this article, decay properties of the $P$-wave charmed baryons using the method of light-cone QCD sum rules were studied. But the authors focused on two-body and three-body decays which are kinematically allowed.

Spectrum of singly heavy baryons from a chiral effective theory of diquarks
TL;DR: In this article, the mass spectra of singly charmed and bottom baryons were investigated using a nonrelativistic potential model with a heavy quark and a light diquark, and the masses of the scalar and pseudoscalar diquarks were taken from a chiral effective theory.
