Abstract
Possible manifestation of the family non-universal Zâ² boson effects in lepton polarization in rare, exclusive baryonic ÎbâÎâ+ââ decay is examined. It is observed that the double lepton polarizations PNN, PTT and PTN are sensitive to the Zâ² contribution. Moreover, it is found that the values of the polarized forward-backward asymmetry AFBLL are different in Standard Model (SM) and family non-universal Zâ² model in different regions of q2, and therefore can serve as an efficient tool for establishing new physics beyond the SM.
