摘要：

A simultaneous description of the NN and YN interactions is attempted in the resonating-group formulation of the spin-flavor SU6 quark model, in which the full Fermi-Breit interaction with explicit quark-mass dependence acts between quarks, and all the mesons of scalar and pseudoscalar nonets couple directly to quarks. An overall agreement with the existing data is obtained with few adjustable parameters. In the Lambda p elastic total cross sections, the cusp structure at the Sigma N threshold is strongly enhanced by the antisymmetric LS((-)) force generated from the Fermi-Breit interaction.
