Upper Limit for JΨ→γ +Axion
Year: 1982
Type: article
Abstract: A search has been made with the Crystal Ball Detector for axionlike particles in radiative $\frac{J}{\ensuremath{\Psi}}$ decays. An upper limit on the branching ratio $B(\frac{J}{\ensuremath{\Psi}}\ensuremath{\rightarrow}\ensuremath{\gamma}+a)<1.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ (90% C.L.) is obtained. This result holds for long-lived, noninteracting pseudoscalar or vector particles of mass less than 1 GeV. Thus, this experiment also places stringent limits on the existence of other possible light bosons such as those arising in supersymmetric theories.
