| アブストラクト: |
At a hadron collider such as the LHC, the presence of initial state QCD radiation can have a large impact on signatures for new physics. The best available description of jets from QCD radiation is achieved with a procedure that matches jets from the matrix element and parton shower descriptions of the radiation. While the effects of this matching is in general smaller for higher mass particles, there are many scenarios where such a procedure can be of crucial importance, not only for Standard Model backgrounds, but also for production of gluinos and squarks at the LHC. I will present the matching implementation of MadGraph/MadEvent and Pythia, and discuss the impact of the matching procedures in some key scenarios for New Physics. |
