“…Further in Ref. [2] the authors refined this model by replacing the phenomenological σ rep by one-gluon-exchange (OGE), and a satisfactory description of the KN experimental data was gotten. However, in this hybrid model the one-pion exchange is supposed to be absent, which is true on the hadron level, but is not the case in a genuine quark model study, because the quark exchange effect in the single boson exchanges has to be considered.…”

The chiral SU(3) quark model is extended to include the coupling between the quark and vector chiral fields. The one-gluon exchange (OGE) which dominantly governs the short-range quarkquark interaction in the original chiral SU(3) quark model is now nearly replaced by the vectormeson exchange. Using this model, the isospin I = 0 and I = 1 kaon-nucleon S, P , D, F wave phase shifts are dynamically studied by solving the resonating group method (RGM) equation. Similar to those given by the original chiral SU(3) quark model, the calculated results for many partial waves are consistent with the experiment, while there is no improvement in this new approach for the P 13 and D 15 channels, of which the theoretical phase shifts are too much repulsive and attractive respectively when the laboratory momentum of the kaon meson is greater than 300 MeV.

“…Actually, the KN scattering process had aroused particular interest in the past [4,5,6,7,8] and many works have been devoted to this issue based on constituent quark model. But up to now, most of them can not accurately reproduce the KN phase shifts up to L = 3 in a sufficient consistent way.…”

The isospin I = 0 and I = 1 kaon-nucleon S, P , D, F wave phase shifts are studied in the chiral SU(3) quark model by solving the resonating group method (RGM) equation. The calculated phase shifts for different partial waves are in agreement with the experimental data. Furthermore, the structures of the ∆K states with L = 0, I = 1 and I = 2 are investigated. We find that the interaction between ∆ and K in the case of L = 0, I = 1 is attractive, which is not like the situation of the N K system, where the S-wave interactions between N and K for both I = 0 and I = 1 are repulsive. Our numerical results also show that when the model parameters are taken to be the same as in our previous N N and Y N scattering calculations, the ∆K state with L = 0 and I = 1 is a weakly bound state with about 2 MeV binding energy, while the one with I = 2 is unbound in the present one-channel calculation.

“…In terms of color-spin-flavor matrix elements, this quark-interchange process is equivalent to the elastic process K + p, discussed in Ref. [17]. The most important contributions of H 4 to this channel come from the momentum dependent central and spin-spin (proportional to S 1 ·S 2 ) components, for which…”

The scattering of charmed mesons on nucleons is investigated within a chiral quark model inspired on the QCD Hamiltonian in Coulomb gauge. The microscopic model incorporates a longitudinal Coulomb confining interaction derived from a self-consistent quasi-particle approximation to the QCD vacuum, and a traverse hyperfine interaction motivated from lattice simulations of QCD in Coulomb gauge. From the microscopic interactions at the quark level, effective meson-baryon interactions are derived using a mapping formalism that leads to quark-Born diagrams. As an application, the total cross-section of heavy-light D-mesons scattering on nucleons is estimated.
