✦ Synopsis

Structure of hypernuclei provides valuable information on baryon-baryon interactions. We have studied the ΛN spin-dependent interactions from precise level structure of pshell Λ hypernuclei by means of a recently-developed technique of hypernuclear γ-ray spectroscopy with the germanium detector array, Hyperball. The strengths of the spinspin, spin-orbit, and tensor interactions have been experimentally determined from 7 Λ Li, 9 Λ Be, and 16 Λ O hypernuclear level energies. Consistency check of the strength parameters has been also made with more p-shell hypernuclear data. Experimental results on double Λ hypernuclei and Σ hypernuclei have also provided information on ΛΛ and ΣN interactions.

The weak nonmesonic decay of A hypernuclei gives information on the strangeness changing weak baryon baryon interaction. The parity violation of the process has been studied by observing weak nonmesonic decay of polarized A hypernuclei. Study of the inverse process pn --+ pA gives much cleaner infor

We study S-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons using the lowest order chiral Lagrangian. In the S = 1 sector, we find an attractive interaction in the ∆K channel with I = 1 while it is repulsive for I = 2. The attractive interaction leads to a pole in the s

The correlation between baryon number and strangeness elucidates the nature of strongly interacting matter. This diagnostic can be extracted theoretically from lattice QCD calculations and experimentally from event-by-event fluctuations. The analysis of present lattice results above the critical tem
