نویسنده
چکیده
We study the binding energy and the width of the Θ in nuclei, associated to the KN and KπN components. The first one leads to negligible contributions while the second one leads to a sizeable attraction, enough to bind the Θ in nuclei. Pauli blocking and binding effects on the KN decay reduce considerably the Θ decay width in nuclei and medium effects associated to the KπN component also lead to a very small width, as a consequence of which one finds separation between the bound levels considerably larger than the width of the states.

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...

We study the interaction of the Θ + pentaquark with nuclear matter associated to the KN decay channels and to the two meson cloud. We find that the potential is attractive and could be strong enough to lead to the existence of Θ + nuclear bound states.

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.
