Abstract
The sensitivity of scintillators to grand unification monopoles and other supermassive charged particles is inferred from measurements of scintillation by recoil protons with velocities as low as 2.5×c. No evidence for a response cutoff is observed at velocities extending well below the electronic-excitation threshold of 6×c expected from two-body kinematics. The relevance of these measurements to searches for supermassive relic charged particles is discussed.
