We formulate a QCD sum rule to find the three momentum dependence of the peak position of the vector meson spectral density in nuclear medium. We find less than 2 % (0.1 %) shift of the peak position at nuclear matter density and at ($q =0.5$GeV/c) for the $\rho,\omega (\phi$) mesons. However, at higher density and three momentum, its effect becomes non-negligible. The relevance of our result in the dilepton spectrum in A-A and p-A reaction is discussed.

Polarization dependence of the $\phi$ meson from finite-temperature QCD sum rules
Finite-temperature QCD sum rules predict momentum-dependent mass increases and growing transverse-longitudinal splitting for the phi meson, driven primarily by dimension-four spin-dependent thermal condensates.
