Prediction for CP violation via electric dipole moment of [tau] lepton in [gamma][gamma] [arrow right] [tau] ^sup +^ [tau] ^sup -^ process at CLIC

Abstract Pair production of tau leptons in two photon collision γγ [arrow right] [tau] + [tau] - is studied at CLIC to test CP violating QED couplings of tau leptons. CP violating effects are investigated using tau pair spin correlations which are observed through the hadronic decay of each [tau] in...

Description
Summary:Abstract Pair production of tau leptons in two photon collision γγ [arrow right] [tau] + [tau] - is studied at CLIC to test CP violating QED couplings of tau leptons. CP violating effects are investigated using tau pair spin correlations which are observed through the hadronic decay of each [tau] into πν. Competitive bounds with previous works on the electric dipole moment from CP odd terms have been obtained.
