Formation ofη′(958)-mesic nuclei by the (p,d) reaction

Formation of η′(958) mesic nuclei

In this report, we show the theoretical results of the formation spectra of the η′-nucleus systems in the (p, d) reactions based on the latest theoretical considerations of the η′ properties in nucleus. The results shown here are important to give predictions and supports to the future experiment, and to make clear relations between the η′ mesic nucleus formation spectra and the modifications o...

Formation of η-mesic Nuclei Using the Recoilless (d,He) Reaction

We propose to use the recoilless (d,3He) reaction to produce η-mesic nuclei. This reaction has been used to observe deeply bound pionic states and proven to be powerful recently. We calculate η-mesic bound states in the nucleus using an optical potential and their formation cross section with the Green function method. Then, we carefully check the experimental feasibility. We find that η-mesic ...

Charmed Mesic Nuclei

We show that the D − meson will inevitably form narrow bound states with 208 Pb. The experimental confirmation and comparison with the ¯ D 0 and D 0 will provide distinctive information on the nature of the interaction between the charmed meson and matter. In relativistic models of nuclear structure like QHD [1] or QMC [2–10], the isoscalar-scalar meson, σ, is responsible for a large reduction ...

Production 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...
