Are eta- and omega-nuclear states bound?

الأصل · EN

We investigate theoretically whether it is feasible to detect η- and ω-nucleus bound states. As well as the closed shell nuclei, ¹⁶O, ⁴⁰Ca, ⁹⁰Zr and ²⁰⁸Pb, we also investigate ⁶He, ¹¹B and ²⁶Mg, which are the final nuclei in the proposed experiment involving the (d,³He) reaction at GSI. Potentials for the η and ω mesons in these nuclei are calculated in local density approximation, embedding the mesons in the nucleus described by solving the mean-field equations of motion in the QMC model. Our results suggest that one should expect to find η- and ω-nucleus bound states in all these nuclei.
