We study the pairing Hamiltonian in a set of non degenerate levels. First, we discuss the spontaneous breaking of the U (1) symmetry in the path integral framework in the degenerate situation. Next, in the multilevel case, we obtain approximate, but accurate, expressions for the ground state energy in terms of a few moments of the single particle levels distribution when the system is in a supe...

In-medium properties of the ω meson through ω photoproduction in nuclei Abstract The feasibility to study the in-medium properties of the ω meson in pho-ton induced reactions on nuclei is investigated by means of a semiclas-sical transport model. The calculations are dedicated to an experiment presently being analyzed by the TAPS/Crystal Barrel collaborations. A full coupled-channel treatment o...
