The status of Compton scattering by the nucleon at energies of the first and second resonance is summarized. In addition to a general test of dispersion theories and a precise determination of polarizabilities, the validities of four fundamental sum rules are explored. Recommended averages of experimental values for the electromagnetic polarizabilities and spin-polarizabilities of the nucleon a...

The s-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons is studied in a unitarized coupled channel approach. We obtain a fair agreement for mass and width of several 3 2 − resonances. In particular, the Ξ(1820), the Λ(1520) and the Σ(1670) states are well reproduced. Other resonances are predicted and also the couplings of the observed resonances to the various chan...

We describe full-coupled-channel ab initio calculations among the octet baryons for S = −2 s-shell hypernuclei, 4 ΛΛH, 5 ΛΛH and 6 ΛΛHe. The wave function includes ΛΛ, ΛΣ, NΞ and ΣΣ channels. Minnesota NN , D2 Y N and Nijmegen model D simulated Y Y interactions are used. This is the first attempt to explore the few-body problem of the full-coupled channel scheme for A = 4−6, S = −2 multistrange...
