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.eninfo:eu-repo/semantics/openAccessBeyond Standard ModelCP violationPrediction for CP violation via electric dipole moment of τ lepton in γγ → τ+τ- process at CLICArticle610.1007/JHEP06(2016)1182-s2.0-84977559146Q1WOS:000378933100002Q1
