Experimental test of higher-order QED and a search for excited muon states
Journal Article
·
· Phys. Rev. Lett.; (United States)
The reactions e/sup +/e/sup -/..--> mu../sup +/..mu../sup -/..gamma gamma.. and e/sup +/e/sup -/..--> mu../sup +/..mu../sup -/..gamma.. have been studied at ..sqrt..s = 29 GeV with the MAC detector at the SLAC storage ring. The measured cross sections, charge asymmetry, and invariant-mass distributions are in good agreement with the predictions of QED theory. Limits are derived for the production of excited muon states.
