Eta-mesic Nucleus: a New Form of Nuclear Matter *
نویسنده
چکیده
Formation of η-mesic nucleus, a bound state of an η meson in a nucleus, is reviewed in this paper. Three different theoretical approaches are used to calculate the binding energies and widths of such nuclei. The effect of η-mesic nucleus in pion double-charge-exchange reaction is discussed. Experimental efforts by different groups to detect the nucleus are also discussed. The ramifications of the theoretical and experimental studies of the bound state of η in a nucleus are pointed out.

Level crossing of particle-hole and mesonic modes in eta mesic nuclei
The prominent feature of the η meson is that it couples dominantly to the N(1535) (S11) resonance at threshold energies. The low-momentum η meson would then mainly excite N–nucleon-hole (N-h) states in nuclear matter. Therefore the η meson nuclear dynamics is sensitive to modifications of nucleon and N properties in medium. If some medium effects and/or a density increase bring the N-h state do...
متن کاملProduction and Decay of Eta-mesic Nuclei
Using the Green function method, binding effects on produced η-mesons in the two-stage reaction γ + A → N + η + (A − 1) → N + (πN) + (A − 2) are studied. The energy spectrum of the correlated πN pairs which arise from decays of η’s inside the nucleus is strongly affected by an attractive η-nucleus optical potential. Its resonant behavior gives a clear signal of formating intermediate η-mesic nu...
متن کاملω-nucleus bound states in the Walecka model
Using the Walecka model, we investigate theoretically whether an ω meson is bound to finite nuclei. We study several nuclei from He to Pb, and compare the results with those in the quark-meson coupling (QMC) model. Our calculation shows that deeper ω-nucleus bound states are predicted in the Walecka model than in QMC. One can expect to detect such bound states in the proposed experiment involvi...

The anti-D meson self-energy is evaluated self-consistently, using unitarized coupledchannel theory, by computing the in-medium meson-baryon T -matrix in the C = −1, S = 0 sector. The heavy pseudo-scalar and heavy vector mesons, D̄ and D̄, are treated on equal footing as required by heavy quark spin symmetry. Results for energy levels and widths of D mesic atoms in 12C, 40Ca, 118Sn and 208Pb are ...
متن کاملη-mesic nuclei in relativistic mean-field theory
With the η-nucleon (ηN) interaction Lagrangian deduced from chiral perturbation theory, we study the possible η-mesic nuclei in the framework of relativistic mean-field theory. The η single-particle energies are sensitive to the ηN scattering length, and increase monotonically with the nucleon number A. If the scattering length is in the range of a = 0.75 ∼ 1.05 fm and the imaginary potential V...
