    33== W and H+ polarizations in top decays  ==
    4    1. Generate %$e^+e^-  \to t \bar t$% at threshold and force the tops to decay leptonically (to %$e$% or %$\mu$%).
    5       a. Compare the charged and neutral lepton %$p_T$% (or energy) distributions with those shown in the MC lectures.
    6       a. Explain why the neutrinos tend to have higher %$p_T$% than the charged leptons.
    7       a. How would things change if the decay went via %$t\to b H^+$% with %$m_{H^+}=m_W$%? Check by using
