Charmed baryons in a quark model with hyperfine interactions
TLDR
In this article, a quark model based on quantum chromodynamics and tested against noncharmed baryons was employed to predict masses and decay rates of ground-state and excited quarks containing one charmed quark.Abstract:
We employ a quark model based on quantum chromodynamics and tested against noncharmed baryons to predict masses and decay rates of ground-state and excited baryons containing one charmed quark. Among other conclusions, the calculations indicate that the orbitally excited ${\ensuremath{\Lambda}}_{c}$ $\frac{1}{{2}^{\ensuremath{-}}}$ analogous to the $\ensuremath{\Lambda}(1405)$ is stable against strong decays.read more

Baryons in a relativized quark model with chromodynamics
Simon Capstick,Nathan Isgur +1 more
TL;DR: The three quark system is studied in a relativized version of the quark potential model with chromodynamics and the spectrum of baryons is described with parameters consistent with those of an analogous study of meson spectroscopy.

Hadronic molecules
TL;DR: In this article, the authors review experimental evidences of various candidates of hadronic molecules, and methods of identifying such structures Nonrelativistic effective field theories are the suitable framework for studying hadronic molecule, and are discussed in both the continuum and finite volumes.

Heavy baryons in a quark model
Winston Roberts,Muslema Pervin +1 more
TL;DR: In this article, a quark model is applied to the spectrum of baryons containing heavy quarks, and the model gives masses for the known heavy quark that are in agreement with experiment, but for the doubly-charmed baryon Ξcc, the model prediction is too heavy.
