| Abstract | We calculate the contributions of extended technicolor (ETC) interactions to the CP violation asymmetry parameter delta in top quark pair production, delta = sigma [ee to t(-)t(-)]- sigma [ee to t (+)t(+)]/ sigma (ee to tt), in the topcolor-assisted multiscale technicolor (TOPCMTC) model using the new LEP value of R/sub b/. We give numerical results. Our results show that ETC interactions can produce significant effects for CP violation for a certain range of the parameters in the TOPCMTC model. For 500 GeV<or= square root s<or =1500 GeV, the value of parameter delta is in the range 8.65*10(/sup -/3)<or= delta <or=1.09*10(/sup -/2). We expect that this effect may be testable in future NLC experiments. (16 refs). |
