Heavy quark polarizations of e+e-→q(q)over-barh in the general two Higgs doublet model -: art. no. 077702

The polarizations of the heavy quark (q=t or b) in the process e(+)e(-)-->q (q) over barh have been calculated in the general two Higgs doublet model. The CP violating normal polarization of the top quark can reach 8%, and 2-3 % for the bottom quark, while it is zero in the standard model. The longitudinal and transverse polarizations of the bottom quark can be significantly different from those in the SM and consequently could also be used as a probe of new physics.
