On the search for weak decays of heavy quarkonium in dedicated heavy-quark factories

  • Published:

Abstract

The possibility of detecting weak decays of charmonium and bottomonium in dedicated heavy-quark factories is examined. First, semi-leptonic and two-body non-leptonic decays of heavy quarkonium are analyzed theoretically on the basis of the spin symmetry of heavy hadrons. Finally, possible procedures for conducting the experimental search are proposed and the requested detector requirements are discussed.
