Experimental constraints on left-right symmetric models from muon decay. Academic Article uri icon


  • The TWIST Collaboration has completed a new measurement of the energy-angle spectrum of positrons from the decay of highly polarized muons. A simultaneous measurement of the muon decay parameters , , and P()() tests the standard model in a purely leptonic process and provides improved limits for relevant extensions to the standard model. Specifically, for the generalized left-right symmetric model |(g(R)/g(L))|<0.020 and (g(L)/g(R))m(2)>578GeV/c(2), both 90% C.L.
