Spin correlations in ttbar production

1.

Use MadGraph at tree level to generate 10k parton-level events for pp>tt~>bb~mu+e-vmve~, i.e., the 2->6 complete matrix element at the Tevatron and the LHC.

2.

Study the one-particle and two-particle inclusive distributions using an event analyser (MadAnalysis or Chameleon or anything you like).

3.

Consider the angles %$\theta_{+,-}$ defined in the lecture and plot the 2 dimensional distribution. Apply invariant mass cuts to enhance the correlations.
