Available in PDF, EPUB and Kindle. Book excerpt: Transverse polarization (TP) enables novel CP violation search in the inclusive process e+e− → A + X. When the A spin is unobserved and m{sub e} neglected, only (pseudo-)scalar or tensor currents associated with a new-physics scale [Lambda] can lead to CP-odd observables at leading order in the couplings from interference with [gamma] and Z in the presence of TP. Without TP, these couplings can be probed only at higher order, and with loss of statistics entailed by the measurement of A polarization. For e+e− → t{bar t}, an azimuthal CP asymmetry can yield at 90% C.L. a bound on [Lambda] of ≈ 10 TeV for √s = 500 GeV and ∫ dtL = 500 fb−1 with perfect TP.
