Book excerpt: We discuss the test of CP and CPT violation in Tau decay without using the polarized electron beam by comparing partial fractions of tau( - ) and tau(+) decay into channels with strong final state interactions. For example, gamma(tau( - ) right arrow pi( - ) + pi(0) + nu) not equal gamma(tau(+) right arrow pi(+) + pi(0) + nu) signifies violation of CP. The optimum energy to investigate CP violation in tau decay is discussed. We conclude that this energy is a few MeV below psi(2s) in order to avoid the charm contribution and over abundance of hadrons at the psi(2s) peak.
