I have a project about measurement of spin polarization and correlation of top quark pairs. I am gonna analyze real collision data from LHC. Before that I had one class about undergraduate level particle physics.
Yet, I literally did not understand how can I do the calculations of spin of a particle or what I am gonna do. I found lots of articles and PhD. thesis but they are not concerning teaching or derivation of the analysis.
I also did not grasp the idea of spin correlation. What is it ? Why do I need it ? Small intro or a textbook suggestion would be good.
