Abstract
- The reactione+e−→μ+μ− has been studied with the PLUTO detector at the c.m. energy of 34.7 GeV, based on an integrated luminosity of 46 pb−1. The total cross section agrees with QED predictions, and the corresponding lower limits for theΛ+ andΛ− QED cutoff parameters are 267 and 126 GeV respectively (95% c.l.). A forward-backward asymmetry parameterA=−(13.4±3.1±
