Detailed Description

Description:

used for single top t-channel events generated with MadEvent and matched the "Karlsruhe way" filter on 2->2 process events, where the crucial candidate (the 2nd b quark) is not available until parton showering is done filter criterion: transverse momentum of 2nd b quark "pT < pTMax" -> event accepted! How-To: include STFilter.cfg in your .cfg, replace pTMax by the desired value, include module "STFilter" in outpath Implementation: <Notes on="" implementation>="">
