Description

The quantity Pμπξ, where ξ is one of the muon decay parameters and Pμπ is the degree of muon polarization in pion decay, has been measured. The value Pμπξ=1.0003±0.0006(stat.)±0.0038(syst.) was obtained. This result agrees with previous measurements but is over a factor of 2 more precise. It also agrees with the Standard Model prediction for Pμπξ and thus leads to restrictions on left-right symmetric models
