The interaction energies between two baryons at short distance in different flavor channels are calculated from the constituent quark model (CQM) and are compared with the recent lattice QCD (LQCD) results for baryon–baryon potentials at short distance. We consider the six-quark system with two strange quarks and focus on the quantum numbers, (Flavor, Spin) = (1, 0), (8, 1), (10, 1), ( 10 ¯ , 1) and (27, 0). The interaction energy is defined by subtracting out isolated baryon masses and relative kinetic energy of two baryons from the total energy of a compact six-quark state. We introduce interaction energy ratio between different flavors as a useful measure to test the prediction of CQM. We find that the ratios in CQM show good agreement with those in LQCD, which indicates that the short range part of the baryon-baryon interaction can be understood qualitatively in terms of the Pauli principle and spin-dependent color interaction among constituent quarks.

We study the short-distance part of the intrinsic three-nucleon interaction in a constituent quark model with color-spin interaction. For that purpose, we first calculate the transformation coefficient between the tribaryon configuration and their corresponding three-baryon basis. Using a formula for the intrinsic three-body interaction in terms of a tribaryon configuration, we find that after subtracting the corresponding two-baryon contributions, the intrinsic three-body interaction vanishes in flavor SU(3) symmetric limit for all quantum numbers for the three nucleon states. We further find that the intrinsic three-body interaction also vanishes for flavor-spin type of quark interaction. [ABSTRACT FROM AUTHOR]

Utilizing a quark model characterized by parameters that effectively replicate the masses of ground state hadrons, we illustrate that (u s) or (d s) diquarks exhibit greater compactness in comparison to (u d) diquarks. Concretely, the binding energy of the (u s) diquark - defined as the diquark's mass minus the combined masses of its individual quarks - is found to be stronger than that of the (u d) diquark. This heightened attraction present in (u s) diquarks could lead to enhanced production of Ξ c / D particles in high-energy pp or ultrarelativistic heavy-ion collisions. [ABSTRACT FROM AUTHOR]
