Spectroscopy of eta'-nucleus bound states at GSI-SIS
arXiv:1208.4932 · doi:10.1051/epjconf/20123702005
Abstract
The eta' meson mass may be reduced due to partial restoration of chiral symmetry. If this is the case, an eta'-nucleus system may form a nuclear bound state. We plan to carry out a missing-mass spectroscopy with the 12C(p,d) reaction at GSI-SIS. Peak structures corresponding to such a bound state may be observed even in an inclusive measurement, if the decay width is narrow enough.
