Meson mass modification in strange hadronic matter
نویسندگان
چکیده
We investigate in stable strange hadronic matter (SHM) the modification of the masses of the scalar (σ, σ∗) and the vector (ω, φ) mesons. The baryon ground state is treated in the relativistic Hartree approximation in the nonlinear σ-ω and linear σ∗-φ model. In stable SHM, the masses of all the mesons reveal considerable reduction due to large vacuum polarization contribution from the hyperons and small density dependent effects caused by larger binding.

Collective modes in strange and isospin asymmetric hadronic matter
We study the propagation of non-strange and strange meson modes in hadronic matter considering isospin and/or strangeness mixing induced by quantum fluctuations in the medium. Baryons are described using the Quark Meson Coupling model extended to include couplings with strange quarks. In particular we evaluate the dependence of the meson masses on the baryonic density, the strangeness fraction ...
متن کاملA Strange Mesonic
The strange-quark vector current ρ-to-π meson transition form factor is computed at one-loop order using strange meson intermediate states. A comparison is made with a φ-meson dominance model estimate. We find that one-loop contributions are comparable in magnitude to those predicted by φ-meson dominance. It is possible that the one-loop contribution can make the matrix element as large as thos...
متن کاملMedium 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...

We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied. The interaction between quarks and vector mesons destabilizes the strange quark matter. If the strength of the vector coupling is the same as in hadronic matter, strangelets can not be formed. For the case of β equilibrium, t...
متن کاملResonances from PHSD
The multi-strange baryon and vector meson resonance production in relativistic nucleus-nucleus collisions is studied within the parton-hadronstring dynamics (PHSD) approach which incorporates explicit partonic degreesof-freedom in terms of strongly interacting quasiparticles (quarks and gluons) in line with an equation-of-state from lattice QCD as well as the dynamical hadronization and hadroni...
