Abstract
We derive strangeness −2 baryon-baryon interactions from a chiral constituent quark model including the full set of scalar mesons. The model has been tuned in the strangeness 0 and −1 two-baryon systems, providing parameter free predictions for the strangeness −2 case. We calculate elastic and inelastic NΞ and ΛΛ cross sections which are consistent with the existing experimental data. We also calculate the two-body scattering lengths for the different spin-isospin channels.
