Observation of CP Violation in the B0 Meson System: Phys. Rev. Lett. 87, 091801 (2001).
The study of CP violation in B-decays places higher demands on the technology of hadron identification than do other high-energy-physics experiments. Accordingly Prof. McDonald has been involved for some time in R&D of novel devices for hadron identification, especially those based on detection of UV light with thin-film CsI photocathodes.
A precursor to a muon collider, with an exciting physics program of its own, is a neutrino factory.
Much of my activity in this area concerns novel options for
