for a given parameters file. The code is set up to dump unsatisfactory events in the output logfile for debugging purposes.

Params Files

Run information is specified in a .params file. The top line of a .params file should look like:

14000D0 5000 10 500 p p

In this case, 14000 is the centre of mass energy (in GeV), 5000 is the number of events to generate, 10 is the number of events to printout at the start of the run, 500 is the subsequent printout interval, and "p p" is the initial state appropriate to the LHC.

The code was initially designed to generate vector boson (WW) fusion events, and it has been adapted in stages to generate ttH instead, with some additional modifications. In particular, the histogramming aspect of the initial VBF code (which used the Pythia data to prepare an hbook file) has been disabled.
