Exercise 4

In this exercise I should plot the distributions of the p_T of the particle with maximal p_T in each event for -8.0< η <8.0 and no restrictions on p_T.

The setup of Rivet is similar to ExerciseThree, the only difference is the .cc file that is used and the name of the analysis in rivet_cfg.py.

In general the solution is very similar to the solution of ExerciseThree. For ExerciseFour I made a .cc file for the GeneratorInterface/RivetInterface/src/ directory. I do not need an .aida file since the bin sizes are determined in the .cc file. The rivet_cfg.py file was modified to run 100000 events, and to exclude single diffractive events by setting MSUB(92) = 0 and MSUB(93) = 0.

The results are in ex4.root, and using the root macro ex4_plot.C I made the plots shown in the short summary of the results.
