Abstract: The experimental setup and results of the first search for invisible decays of orthopositronium (o-Ps) confined in a vacuum cavity are reported. No evidence of invisible decays at a level $\mathrm{Br}(\mathrm{o}\text{\ensuremath{-}}\mathrm{Ps}\ensuremath{\rightarrow}\text{invisible})l5.9\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$ (90% C.L.) was found.… read more here.

DOI: 10.1103/physrevd.99.032008
Abstract: This paper reports results from a search for nucleon decay through invisible modes, where no visible energy is directly deposited during the decay itself, during the initial water phase of SNO+. However, such decays within… read more here.

DOI: 10.1103/physrevlett.120.151301
Abstract: This Letter reports the results from a haloscope search for dark matter axions with masses between 2.66 and 2.81 μeV. The search excludes the range of axion-photon couplings predicted by plausible models of the invisible axion.… read more here.
