چکیده

We investigate theoretically whether it is feasible to detect η-and ω-nucleus bound states. As well as the closed shell nuclei, 16 O, 40 Ca, 90 Zr and 208 Pb, we also investigate 6 He, 11 B and 26 Mg, which are the final nuclei in the proposed experiment involving the (d, 3 He) reaction at GSI. Potentials for the η and ω mesons in these nuclei are calculated in local density approximation, embedding the mesons in the nucleus described by solving the mean-field equations of motion in the QMC model. Our results suggest that one should expect to find η-and ω-nucleus bound states in all these nuclei.

Thermo Field Dynamics for inhomogeneous systems is generalized to quantum fields with a continuous single-particle mass spectrum. The modification of the hamiltonian in states with a local thermal Bogoliubov symmetry is used to calculate thermal conductivity and diffusion coefficient of pions interacting with hot, compressed nuclear matter.

The properties of vector mesons in nuclear matter are discussed. Results for the momentum dependence of the ρ-meson self energy in matter due to ρN interactions are presented, and consequences for the production rate of e+e− pairs in hot and dense matter are discussed. I also examine the constraints imposed by elementary processes on the widths of ρ and ω mesons in nuclear matter, and conclude ...
