Effects of transverse beam polarization on anomalousμ−eevents

We present differential cross sections, in the colliding-beam rest frame, for $\mu -e$ pair production by leptonic decays of (a) heavy-spin-½-lepton pair, (b) spin-1-boson pair, themselves produced via one quantum annihilation. We find that study of the anomalous $\mu -e$ events in the polarized $e^{+}{e}^{-}$ collisions is quite useful in understanding the dynamics behind these events.
