High sensitivity tests of the standard model for electroweak interactions. Scientific progress report, 16 January 1991--15 January 1992
The work done on this project was focussed mainly on LAMPF experiment E969 known as the MEGA experiment, a high sensitivity search for the lepton family number violating decay {mu} {yields} e{gamma} to a sensitivity which, measured in terms of the branching ratio, BR = [{mu}{yields}e{gamma}]/[{mu}{yields}e {nu}{sub {mu}} {nu}{sub e}] {approx}10{sup {minus}13} is over two orders of magnitude better than previously reported values. The work done on MEGA during this period was divided between that done at Valparaiso University and that done at LAMPF. In addition, some contributions were made to a proposal to the LAMPF PAC to perform a precision measurement of the Michel {rho} parameter, described below.
