In the Green's function method of the distorted wave impulse wave approximation with the local optimal Fermi averaging t-matrix, we can describe the Ξ − production spectra in the continuum and bound state region reasonably well. Predictions to the high resonlution spectra at J-PARC suggest that we should observe Ξ − bound state peak structure in (K − , K +) spectra in light nuclear targets such as 12 C and 27 Al.

In order to include the nucleon and hyperon potential effects in Fermi averaging, we introduce the local optimal momentum approximation of target nucleons. We can describe the quasi free Λ, Σ and Ξ production spectra in a better way than in the standard Fermi averaged t-matrix treatments.

Both of baryon and finite coupling correction are found to have effects to extend the hadron phase to a larger µ direction relative to Tc. In a chiral RMF model with logarithmic sigma potential derived in the strong coupling limit of lattice QCD, we can avoid the chiral collapse and normal and hypernuclei properties are well described.

In the Green's function method of the distorted wave impulse wave approximation with the local optimal Fermi averaging t-matrix, we can describe the Xi production spectra in the continuum and bound state region reasonably well. Predictions to the high resonlution spectra at J-PARC suggest hat we should observe Xi bound state peak structure in (K-,K+) spectra in light nuclear targets such as 12C and 27Al.
