Detailed Description

The XComb class stores all information about the generation of a hard sub-proces for a given pair of incoming particles, a pair of extracted partons, total parton-parton energy squared and a PartonExtractor object.

When an event is generated, the objects used in the generation can be assigned an XComb object for easy acces to the corresponding information. To facilitate this, the corresponding classes inherits from the LastXCombInfo class which provides the relefant access functions.
