Description
We investigate the spectral function of the $\phi$ meson in hot and dense nuclear matter created in low-energy heavy-ion collisions, where the existence of the medium's rest frame leads to a splitting between the transverse and longitudinal modes of vector mesons. We compute the transverse and longitudinal spectral functions within the framework of QCD sum rules and apply them to the $\phi$-meson yield measured in future experimental facilities such as FAIR, HIAF, and J-PARC.
