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.
