Abstract: | We examine the left-right and azimuthal polarization asymmetries of lepton pairs produced ine + e ? ande ? e ? interactions as probes of new physics resulting fromE 6 theories. The asymmetries are calculated and compared for the processese + e ?→µ + µ ?,e + e ?→e + e ?,e ? e ?→e ? e ?, ande + e ?→L + L ? whereL is either anE 6 exotic, mirror, or fourth generation heavy lepton. Our results show that lepton polarization asymmetries can be used to easily distinguish differentE 6 models and can be used to distinguish among possible new heavy leptonsL. |
