Detailed Description

Simplified interface to the Rivet program. Remember to link with pythia and -lhepmcinterface -lHepMC -lRivet

Usage: (1) Create an object giving the pythia object and a filename as arguments. (2) Repeatedly specify (the name of an) analysis with the addAnalysis() function, possibly with analysis parameters. (3) initialize the underlying Rivet object with the init() function. (4) Analyze an event with the operator() function. (5) Dump the histograms to a file with the done() function.

Constructor & Destructor Documentation

Pythia8Rivet ( Pythia &  pytin, string  fname  )

inline

The constructor needs to have the main Pythia object, and the name of the file where the histograms are dumped.

~Pythia8Rivet ( )

inline

The destructor will write the histogram file if this has not already been done.

Member Function Documentation

void addAnalysis ( string  ana )

inline

Add the name of an analysis to be performed, with a list of analysis parameters.

void done ( )

inline

Writes histograms to file and deletes the Rivet object. Does nothing if Rivet was not initialized.

void dump ( int  period, string  fname = ""  )

inline

Set Rivet dump period and file name for intermittent histograms. If no dumpfile given, the default output file is used.

void operator() ( )

inline

Analyze the default Pythia event. Will do nothing if Rivet has not been intialized.
