$τ$ Anomalous Couplings and Radiation Zeros in the $e^+e^- \to τ\barτγ$ process
Abstract
Description
The process $e^+e^- \to τ\barτγ$ contains configurations of the four-momenta for which the scattering amplitude vanishes (Radiation Zeros or Null Zone). These Radiation Zeros only occur for couplings given by a gauge theory, in particular the standard model. Therefore they are sensitive to physics beyond the standard model as the anomalous magnetic and weak moment of the $τ$ lepton. In this article we compute the effect of these anomalous interactions on the Radiation Zeros in the above mentioned process.
