  "abstract": "We obtain the width of the $\\omega$ meson in dense nuclear matter by taking into account (i) the free decay of the $\\omega$ into three pions, which is dominated by $\\rho \\pi$ mode, (ii) the processes induced by a vector-baryon interaction dominated by vector meson exchange, and (iii) the $\\omega \\to K \\bar K$ mechanism in matter. The $\\omega$ meson develops an important width in matter, coming from the dominant $\\omega \\to \\rho\\pi$ decay mode, with a value of $121 \\pm 10$ MeV at normal nuclear matter density for an $\\omega$ at rest. At finite momentum, the width of the $\\omega$ meson increases moderately with values of 200 MeV at 600 MeV/c.",
