 Click the tab below to see the code. This code may look rather long, but it does a lot: It reads the truth-level events, reconstructs jets, and makes plots of the pT (differential cross section), Rapidity distribution and the invariant mass of the 2 jets. It also saves the image in SVG file  and an XML file for examination:
