     7Compute analytically the partonic cross sections for %$q \bar q \to t \bar t$% and %$g g \to t \bar t$% for t spin 1/2 and spin 0 at the tree level. Check your results against the LO results available in the literature:

     23Consider the behaviour at threshold and also the relative sizes of the cross sections for corresponding masses.

     27Use any MC at tree level to calculate the cross sections for tops and stops at the Tevatron and the LHC. Make plots of the distributions and in particular of %$m_tt$%.
