The σ meson mass and width are studied at finite baryonic density in the framework of a chiral unitary approach which successfully reproduces the meson meson phase shifts and generates the f 0 and σ resonances in vacuum.

applying the variational method, the spinless reduced bethe-salpeter (rbs) equation is solved for the mesonic systems, and the mass spectra are obtained. the method is applied to the hamiltonian with the gaussian and hydrogen-type trial wave functions, and different potential models are examined. the results for the different potentials are in challenge in light mesons, while they are consisten...

The D-meson properties in dense nuclear matter are studied. The D-meson spectral density is obtained within the framework of a coupled-channel self-consistent calculation assuming, as bare meson-baryon interaction, a separable potential. The Λc(2593) resonance is generated dynamically in our coupled-channel model. The medium modifications of the D-meson properties due to Pauli blocking and the ...
