Remark on CP-violating Polarization Asymmetry of tt-bar via Anomalous Couplings to gamma and Z
arXiv:hep-ph/9810490 · doi:10.1103/PhysRevD.59.037503
Abstract
We calculate the CP-violating polarization asymmetry of tt-bar, delta =[ sigma(ee-bar --> t(-)t-bar(-))-sigma(ee-bar --> t(+)t-bar(+)) ]/ sigma(ee-bar --> tt-bar), for the most general tt-bar gamma/Z couplings without dropping any non-standard contribution. We find that one term which is usually neglected increases with s and will eventually become non-negligible at very high energy.
