A novel method is proposed to measure eta'(958) meson bound states in 11C nuclei by missing mass spectroscopy of the 12C(p,d) reaction near the eta' production threshold. It is shown that peak structures will be observed experimentally in an inclusive measurement in case that the in-medium eta' mass reduction is sufficiently large and that the decay width of eta' mesic states is narrow enough. Such a measurement will be feasible with the intense proton beam supplied by the SIS synchrotron at GSI combined with the good energy resolution of the fragment separator FRS.

  1. Comprehensive study of mass modifications of light mesons in nuclear matter in the three-flavor extended Linear Sigma Model

    nucl-th 2019-08 conditional novelty 6.0 of 10

    Combining the extended Linear Sigma Model with a parity doublet nucleon model, this paper predicts that most light meson masses drop in nuclear matter and favors a chiral invariant mass M0 around 0.8 GeV.

  2. Irrelevance of Anomalous Breaking of Axial U(1) Symmetry and the U(1) Problem

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    The axial U(1) anomaly is not physical, allowing eta and eta' to be NG bosons consistent with the U(1) problem.
