Abstract

The study of Polarized Top quark decay could be considered as a new channel to search for new physics. According to the Standard model (SM) of particle physics, top quark in a cascade process as decays into a bottom quark and -boson so in the following, -boson decays in a lepton pair (or a quark-antiquark) and bottom hadronizes into an observable bottom-flavored hadron (in most cases a B-meson). Through this paper, we first present an overview on the Polarized Top quark decay and then study the Azimuthal correlation between the event plane, formed by the vectors , and the polar plane constructed by the vectors . We will investigate the effect of right-chiral quark current which is absent in the SM. We will show that this non-SM effect leads to nonzero values for the Azimuthal correlation contribution at leading-order perturbation theory.
