ABSTRACT:

The REDTOP experiment is a super-η/η′ factory aiming at exploring physics BSM, and Cold Dark Matter in particular, in the MeV-GeV energy range. This range is, at present, the most unconstrained among the energy regions searched by current and planned experiments. The η and η′ mesons are almost unique in the particle universe. Their quantum numbers are all zero, which occurs only for the Higgs boson and the vacuum (except for parity). In that respect, REDTOP is considered a low-energy Higgs factory. Furthermore, less than 80REDTOP aims at collecting more than 1014 η/yr (1012 η’/yr) in a 3-year running period, corresponding to about five order of magnitude of the current world sample. Such statistics is sufficient for investigating several symmetry violations, and for searching particles and forces beyond the Standard Model, including dark matter, by studying rare decays of the η and η′. Recent physics and detector studies indicate that REDTOP has excellent sensitivity to probe all four portals connecting the dark sector with the Standard Model, a feature reached only by the SHIP experiment at CERN. Furthermore, conservation laws and violation of discrete symmetries can be probed in several ways. REDTOP is the only η/η′ factory being proposed in the world. The advanced design of the detector is the key of the experiment. A modest proton beam with low power (30 W) is required. Recent physics and detector studies indicate that REDTOP has excellent sensitivity to probe all four portals connecting the dark sector with the Standard Model. Furthermore, conservation laws and violation of discrete symmetries can be probed in several ways. The physics program and the detector for REDTOP will be discussed during the presentation.
