Özet

Pair production of tau leptons in two photon collision gamma gamma -> 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 pi nu. Competitive bounds with previous works on the electric dipole moment from CP odd terms have been obtained.
