Title:     Measurement of the Michel Parameter Rho in Muon Decay

Abstract: The TWIST collaboration is improving the precision on the characterization of normal muon decay through measurements of the decay parameters rho, delta and P_mu*xi.  The Michel parameter rho describes the shape of the momentum spectrum of the positron.  TWIST's ultimate goals include measuring rho to a precision of a few parts in 10^4.  This is facilitated by an intermediate goal of measuring rho to approximately a part in 10^3.  The analysis of the initial TWIST measurement of rho has been completed.  We find rho consistent with the Standard Model and set improved limits on physics beyond the Standard Model. The detector, procedure, results and implications will be discussed.


Stimulants available 15 minutes before the talk.
