Detailed Description

The HEPRUP class is a simple container corresponding to the Les Houches accord (hep-ph/0109068) common block with the same name. The members are named in the same way as in the common block. However, fortran arrays are represented by vectors, except for the arrays of length two which are represented by pair objects.

Member Function Documentation

void clear

(

)

Clear all members.

The HEPRUP class is a simple container for the Les Houches file init block.

void resize ( int  nrup )

inline

Set the NPRUP variable, corresponding to the number of sub-processes, to nrup, and resize all relevant vectors accordingly.

void resize ( )

inline

Assuming the NPRUP variable, corresponding to the number of sub-processes, is correctly set, resize the relevant vectors accordingly.

Member Data Documentation

int IDWTUP

Master switch indicating how the ME generator envisages the events weights should be interpreted according to the Les Houches accord.

pair<int,int> PDFGUP

The author group for the PDF used for the beams according to the PDFLib specification.

pair<int,int> PDFSUP

The id number the PDF used for the beams according to the PDFLib specification.

vector<double> XERRUP

The statistical error in the cross sections for the different subprocesses in pb.

vector<double> XMAXUP

The maximum event weights (in HEPEUP::XWGTUP) for different subprocesses.
