A search for new light charged particles in photoproduction

Motivated by recent V.A. Nikitin’s reports on observation of new light charged particles with a 2-meter JINR propane bubble chamber we perform an experiment at the LPI electron synchrotron "Pakhra" with the aim to detect such particles in the Bethe–Heitler process. Theoretical limits for m...

Zusammenfassung:Motivated by recent V.A. Nikitin’s reports on observation of new light charged particles with a 2-meter JINR propane bubble chamber we perform an experiment at the LPI electron synchrotron "Pakhra" with the aim to detect such particles in the Bethe–Heitler process. Theoretical limits for masses of new light charged particles of spin 0, 1/2 and 1 arising from precise data on the muon anomalous magnetic moment are recalculated and updated. A geometry of the photoproduction experiment is proposed that optimizes signal-tonoise ratio. First results of the experiment are exposed.
