Novel spectral broadening from vector--axial-vector mixing in dense matter

Abstract

In this write-up we summarize main result of our recent analysis on the mixing between transverse $\rho$ and $a_1$ mesons through a set of $\omega \rho a_1$-type interactions in dense baryonic matter. In the analysis, we showed that a clear enhancement of the vector spectral function appears below $\sqrt{s}=m_{\rho }$ for small three-momenta of the $\rho$ meson, and thus the vector spectrum exhibits broadening.
