In this write-up we summarize main result of our recent analysis on the mixing between transverse ρ and a_1 mesons through a set of ωρa_1-type interactions in dense baryonic matter. In the analysis, we showed that a clear enhancement of the vector spectral function appears below √<s>=m_ρ for small three-momenta of the ρ meson, and thus the vector spectrum exhibits broadening.
