چکیده

Abstract The $\eta N$ interactions are investigated in the hot magnetized asymmetric nuclear matter using chiral SU(3) model and perturbation theory (ChPT). In model, in-medium properties of $\eta$-meson calculated by medium modified scalar densities under influence an external magnetic field. Further, combined approach ChPT, off-shell contributions evaluated from ChPT effective Lagrangian, effect incorporated model. We observe a significant field on mass optical potential $\eta$ meson. deeper mass-shift compared to solo both approaches, no additional is observed due uncharged nature mesons presence

D - mesons in dense nuclear matter

The D-meson properties in dense nuclear matter are studied. The D-meson spectral density is obtained within the framework of a coupled-channel self-consistent calculation assuming, as bare meson-baryon interaction, a separable potential. The Λc(2593) resonance is generated dynamically in our coupled-channel model. The medium modifications of the D-meson properties due to Pauli blocking and the ...

Light Vector Mesons in Nuclear Matter

We summarize the current theoretical and experimental status of the spectral changes of vector mesons (ρ, ω, φ) in nuclear medium. Various approaches including QCD sum rules, effective theory of hadrons and bag models show decreasing of the vector meson masses in nuclear matter. Possibility to detect the mass shift through lepton pairs in γ −A, p−A and A−A reactions are also discussed. Invited ...

Correlations in hot asymmetric nuclear matter

The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green’s functions. The internal energy and the momentum distributions of protons and neutrons are studied as a function of the density and the asymmetry of the system. The proton states are more strongly depleted when the asymmetry increases whe...

Constraints on vector mesons with finite momentum in nuclear matter

Using the QCD operator product expansion, we derive the real part of the transverse and longitudinal vector-vector correlation function with the quantum numbers of the ρ and ω mesons to leading order in density and three momentum (q2) for ω2 → −∞. The operator product expansion provides, through the Borel transformed energy dispersion relation, a model independent constraint for the momentum de...

Valid QCD sum rules for vector mesons in nuclear matter.

QCD sum rules for vector mesons (ρ, ω, φ) in nuclear matter are reexamined with an emphasis on the reliability of various sum rules. Monitoring the continuum contribution and the convergence of the operator product expansion plays crucial role in determining the validity of a sum rule. The uncertainties arising from less than precise knowledge of the condensate values and other input parameters...
