نویسنده
چکیده
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 channels are evaluated.

We present recent progress on the properties of antikaons in nuclei and dense nuclear matter as obtained from two ¯ KN interaction models: one based on the lowest-order meson-baryon chiral lagrangian and the other derived from a meson-exchange picture.

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...

Recent studies within the framework of chiral unitary theory produce the Λ(1520) resonance, among several others, as a dynamically generated resonance from the interaction of the baryon decuplet and the meson octet. The Λ(1520) qualifies as a quasibound state of πΣ(1385) and this has repercussion in some observable quantities. In the present work we show that the γp → K+K−p reaction has a sizea...

We discuss the formation of sand d-wave baryon resonances as predicted by the chiral SU(3) symmetry of QCD. Based on the leading order term of the chiral Lagrangian a rich spectrum of molecules is generated, owing to final-state interactions. The spectrum of sand d-wave baryon states with zero and non-zero charm is remarkably consistent with the empirical pattern. In particular, the recently an...

Using a chiral unitary approach for the meson–baryon interactions, we show that two octets of J π = 1/2 − baryon states, which are degenerate in the limit of exact SU(3) symmetry, and a singlet are generated dynamically. The SU(3) breaking produces the splitting of the two octets, resulting in the case of strangeness S = −1 in two poles of the scattering matrix close to the nominal Λ(1405) reso...
