CP violation in open ttbar production at a linear collider
Abstract
Description
CP-violating asymmetries in the processes e+e- -> t tbar and gamma gamma -> ttbar can provide information about CP-violating couplings of the top quark, whose presence would signal physics beyond the standard model. Work on studies of different asymmetries has been described. Special emphasis has been laid on asymmetries in charged lepton distributions arising from top decay. The effect of longitudinal beam polarization has been discussed. Limits possible on the electric dipole moment of the top quark from different angular asymmetries have been obtained.
