 v1 == ---+ Experimental tests of the spin of the top quark == ==== 1. ==== Compute 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: with ==== 2. ==== Consider the behaviour at threshold and also the relative sizes of the cross sections for corresponding masses. ==== 3. ==== Use 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 %$m_tt$%. ==== 4. ==== Compare your findings with [http://arxiv.org/abs/hep-ph/0002305 Top Spin and experimental tests], by Ed Berger and Tim Tait. -- Main.FabioMaltoni - 03 Dec 2008
