A proposed Chinese charm factory could detect heavy neutral leptons from axionlike-particle decays with a displaced-vertex search, reaching electron-neutrino mixing one to two orders of magnitude below current bounds.
Computes production cross sections and sensitivity limits for heavy ALPs in light-by-light scattering at FCC-hh across pp, pPb, and PbPb modes.
