The Michigan L3 group is presently active in several areas of Z analysis, including studies of b quark production and decay, tau lepton decays, and final state photon radiation from quarks and tau leptons. When the LEP beam energy increases, the Michigan group will contribute to precise measurements of the W boson mass. The group also plans to study W production dynamics, using the leptonic W decays to probe the delicate mechanism underlying electroweak unification.

Riles has also recently joined the COSMOS effort at Fermilab, along with several other Michigan physicists (Ball, Levin, McKee, Roe, Tarle, and Thun), to search for oscillations of muon neutrinos into tau neutrinos. The experiment should start taking data at the turn of the millenium. In addition, Riles participates in ongoing studies of the physics potential of a 1 TeV linear electron-positron collider.
Collaborators: T. Azemoon, R.C. Ball, H.R. Gustafson, L. Jones, B. Roe.
L3 Graduate Students: A. Button, C. Leggett, R. Moore, O. Rind, Y. Zhou
