Surprising theoretical results on the decay rate of the /tau/ lepton
Conference
·
OSTI ID:6606245
Corrections to the naive prediction for the inclusive semihadronic decay rate of the /tau/ lepton contain several surprises: electroweak corrections are significant, nonperturbative QCD corrections can be treated systematically, and the order ed /sub s/T perturbative QCD corrections are enormous. The possibility of precise theoretical predictions of the decay rate is discussed. 10 refs.
