We determine the influence of the three-body force and the medium modification of meson masses on pairing in nuclear and neutron matter. A reduction of the pairing gap is found and increasing with density. PACS: 21.65.+f, 24.10.Cn Typeset using REVTEX

Recent advances in the study of pd radiative capture in a wide range of center-of-mass energy below and above deuteron breakup threshold are presented and discussed.

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 have performed shell-model calculations starting from the CD-Bonn free nucleon-nucleon (N N) potential and making use of a new approach for the calculation of the effective interaction. This consists in deriving from the N N potential a low-momentum effective potential V low−k , defined within a given cutoff momentum Λ. Being a smooth potential it can be used directly in nuclear structure ca...
