Description

We have searched for the exotic decay of orthopositronium into a photon and a neutral boson Φ, without any assumptions on its lifetime. Our negative result rules out unambiguously the possibility of this exotic decay being the origin of the reported discrepancy of the orthopositronium decay rate. (orig.)
