On Alpha-Clustering in Nuclear Matter

Nuclear alpha-clustering, superdeformation, and quasimolecular resonances

Nuclear alpha-clustering has been the subject of intense study since the advent of heavy-ion accelerators. Looking back for more than 40 years we are able today to see the connection between quasimolecular resonances in heavy-ion collisions and extremely deformed states in light nuclei. For example superdeformed bands have been recently discovered in light N=Z nuclei such as 36Ar, 40Ca, 48Cr, a...

Alpha matter on a lattice

We obtain the equation of state of interacting alpha matter and the critical temperature of Bose-Einstein condensation of alpha particles within an effective scalar field theory. We start from a non-relativistic model of uniform alpha matter interacting with attractive two-body and repulsive three-body potentials and reformulate this model as a O(2) symmetric scalar φ6 field theory with negativ...

Hadronization in Nuclear Matter

Nuclei are unique analyzers of the space-time development of jets at early stage. We argue that the gluon bremsstrahlung, rather than the color string, is the main mechanism of hadronization of highly virtual quarks produced in a hard interaction. It results in an energyand time-independent density of energy loss, like a color string, but steeply dependent on the quark virtuality. Effects of fo...

Dibaryons in Nuclear Matter

The possibility for occurrence of a Bose condensate of dibaryons in nuclear matter is investigated within the framework of the Walecka model in the mean-field approximation. Constraints for the ωand σ-meson coupling constants with dibaryons following from the requirement of stability of dibaryon matter against compression are derived and the effect of σand π-meson exchange current contributions...
