    "abstract": "We investigate the screening effects on the nucleon-nucleon elastic cross\nsection inside nuclear matter at zero and finite temperature. The N-N\ninteraction is described phenomenologically via meson exchanges ($\\sigma$,\n$\\pi$ and $\\omega$) in the framework of a relativistic lagrangian model. The\nexpressions for the in-medium meson propagators, which take into account the\neffects of matter polarization and renormalized vacuum polarization, are used\nin the calculation of the various meson contributions to the total cross\nsection in the one-boson exchange approximation. The final expressions allow a\nsatisfactory fit of the Coulomb substracted proton-proton cross section data in\nvacuum. At finite density or temperature the cross section is reduced as\ncompared to the vacuum values and compatible with the existing experimental\nconstraints. At high density the $p$-$p$ differential cross section gets\nincreasingly forward and backward peaked. The $\\sigma$-$\\omega$ mixing plays a\nkey role in the understanding of the results.",
