The ϕ meson with finite momentum in a dense medium
The dispersion relation of the ϕ meson in nuclear matter is studied in a QCD sum rule approach. In a dense medium, longitudinal and transverse modes of vector particles can have independently modified dispersion relations due to broken Lorentz invariance. Employing the full set of independent operat...
