Possible molecular states composed of doubly charmed baryons with coupled-channel effect

Abstract

We systematically investigate the possible molecular states composed of (1) two spin-3 2 doubly charmed baryons, and (2) a pair of spin-3 2 and spin-1 2 doubly charmed baryons. The one-boson-exchange (OBE) model is used to describe the potential between two baryons. The channel mixing effect is considered for the systems with the same quantum number (I(J P )) but different total spin (S) and orbital angular momenta (L). We also study the channel mixing effect among the systems composed of various doubly charmed baryons if they have the same quantum number. Many of the systems are good candidates of molecular states.

Dibaryons: Molecular versus compact hexaquarks *

“…Within the one-boson-exchange model, Zhu et al have undertaken a systematic investigation of singly-and doubly-heavy baryon-baryon combinations [145][146][147][148][149][150]. They find several candidates of loosely bound molecular states in the system [148], for loosely bound deuteron-like states in the and [145] as well as and [146] systems.…”

Is $X(7200)$ the heavy anti-quark diquark symmetry partner of $ X(3872)$?

“…We compute the binding energies and scattering lengths of the Ξ( * ) cc Ξ ( * ) cc system, and show the results in Table V. We find seven bound states, i.e., J P C = 0 −+ Ξcc Ξ cc , J [100] and the Ξ * cc Ξ * cc system [101] have been studied in the OBE model, which show that all of these systems are bound. Assuming heavy quark flavor symmetry, we further investigate their hidden bottom partners…”

Chiral perturbation theory for heavy hadrons and chiral effective field theory for heavy hadronic molecules

“…In Ref. [1142], Yang et al investigated the possible bound states in the Ξ ( * ) cc Ξ ( * ) cc / Ξ( * ) cc systems, and predicted the molecular candidates in the isoscalar and isovector channels.…”
