The dispersion relation of rho meson in hot/dense nuclear matter
نویسندگان
چکیده
The dispersion relation of ρ meson in hot/dense medium is analyzed based on the quantum hadrodynamics model with random phase approximation. The real mass and Debye mass behaviors of ρ meson and σ are discussed and compared. The effective masses of ρ and N decrease with the increase of density. The behaviors of Debye masses ms∗ ρ and m s∗ σ vs density are quite different, which reflect the characteristics of scalar σ and vector ρ mesons, respectively. PACS: 14.40. Cs, 11.55. Fv, 11.10. Wx

Medium effects on the rho meson.
The property of a rho meson in dense nuclear matter is studied using the +CD sum rule. The spectral function appearing on the hadronic side of the sum rule is evaluated in the vector dominance model that takes into account the interaction between the rho meson and the pion. Including pion modification by the delta-hole polarization in the nuclear medium, we find that as the nuclear density incr...
متن کاملRho meson in dense hadronic matter.
The spectral function of a rho meson that is at rest in dense hadronic matter and couples strongly to the pion is studied in the vector dominance model by including the effect of the delta hole polarization on the pion. With the free rho-meson mass in the Lagrangian, we find that both the rho-meson peak and width increase with increasing nuclear density, and that a low-mass peak appears at inva...
متن کاملSpectral Function of ρ in Dense and Hot Hadronic Matter
The spectral function of rho meson in hot/dense hadronic matter is calculated. Different from the pure temperature effect which changes the spectral function slightly, in the hadronic environment with high baryonic chemical potential and high temperature the spectral function becomes narrower and is shifted towards the low invariant mass region significantly. PACS: 14.40. Cs, 25.75. -q It is wi...
متن کاملAntilambda enhancement in ultrarelativistic heavy ion collisions.
In the Walecka model, the antilambda mass in dense nuclear matter is smaller than its value in &ee space. This reduces the threshold for antilambda production in dense matter that forms in the compression stage of ultrarelativistic heavy ion collisions. Because of the large number of mesons produced in the collision, the process KM —+ AN, where M denotes either a pion or a rho meson, is shown t...
متن کاملVector mesons in dense matter
We will summarize the progress in understanding the changes in the vector meson spectral density in nuclear medium using the constraint equations obtained from the Borel transformed dispersion relation and QCD Operator Product Expansion. We will discuss the results for the scalar mass shift and dispersion effects (three momentum dependence) for the light quark system (ρ, ω), the strange quark s...
