Correlations in Exotic Nuclear Matter

In recent years, the interest in correlations inside nuclei became an important issue in nuclear physics. On the theoretical, side several calculations using different models including short-range correlation have been done for nuclear matter. However, there is still not much known about the role of correlations in neutron star matter containing hyperons. In our work we examined dynamical corre...

Nuclear Reaction Studies with Exotic Boron Beams

Spectroscopic investigation, on exotic nuclei, performed in two different experiments with secondary radioactive boron beams are discussed. Spectroscopic factors for the B+n bound-states are obtained by measuring momentum distribution of the B residual nucleus from knockout reaction of the B beam at intermediate energy. The momentum distributions are measured in coincidence with the emited γ-ra...

Semiclassical Description of Exotic Nuclear Shapes

Exotic nuclear structures such as bubbles and tori are analyzed through semiclassical extended Thomas-Fermi calculations with the Skyrme force SkM. The variational equations for neutron and proton densities are solved fully self-consistently in spherical (bubbles) and cylindrical (tori) symmetries. The possible existence of bubble configurations in some astrophysical scenarios is discussed. The...

PAMELA/ATIC Anomaly from Exotic Mediated Dark Matter Decay

We discuss dark matter decay mediated by exotically charged particles (“exotics”) in a supersymmetric model with two dark matter (DM) components: One is the (bino-like) lightest supersymmetric particle (LSP) χ, and the other is a newly introduced meta-stable neutral singlet N . N decays to χe+e− via a dimension 6 operator induced by a penguintype one loop diagram with the life time of 1026 sec....
