Quark Models of the Nuclear Force*
Quark models of the two-nucleon interaction are reviewed with particular emphasis on calculations in the MIT bag model. 1. Present Status of Quantum Chromodynamics High energy physicists have grown increasingly optimistic in recent years that the gauge theory of colored quarks and gluons, quantum chromodynamics (QCD), will prove to be the underlying theory of hadronic interactions. Although the...
متن کاملDibaryons in the Quark Cluster Model
In the framework of RGM , the binding energy of one channel ∆∆ (3,0) (d *) and ∆∆ (0,3) are studied in the chiral SU (3) quark cluster model. It is shown that the binding energies of the systems are a few tens of MeV. The behavior of the chiral field is also investigated by comparing the results with those in the SU (2) and the extended SU (2) chiral quark models. It is found that the symmetry ...
متن کاملA quark model analysis of the charge symmetry breaking in nuclear force
Abstract In order to investigate the charge symmetry breaking (CSB) in the short range part of the nuclear force, we calculate the difference of the masses of the neutron and the proton, ∆M, the difference of the scattering lengths of the p-p and n-n scatterings, ∆a, and the difference of the analyzing power of the proton and the neutron in the n-p scattering, ∆A(θ), by a quark model. In the pr...
متن کاملH-dihyperon in Quark Cluster Model
The H dihyperon (DH) is studied in the framework of the SU(3) chiral quark model. It is shown that except the σ chiral field, the overall effect of the other SU(3) chiral fields is destructive in forming a stable DH. The resultant mass of DH in a three coupled channel calculation is ranged from 2225 M eV to 2234 M eV .
متن کاملBaryon-Baryon Interaction in the Quark Cluster Model
The quark cluster model approach to the baryon-baryon interaction is reviewed and recent application to the charge symmetry breaking in nuclear force is discussed. According to quantum chromodynamics (QCD), hadrons are bound states of quarks and gluons, and their interactions are governed by the non-Abelian gauge interaction. Their structures are potentially very complex as QCD is strongly inte...
