Simulation of Hjj production via gluon fusion with Herwig++ — •Ken Arnold — Institut für theoretische Physik, Universität Karlsruhe

Gluon fusion processes are the dominant mechanism for Higgs production at the LHC. The azimuthal angle distribution of the two jets in Hjj events provides information about the CP-nature of the Higgs coupling, exploring physics beyond the Standard Model. Due to gluon exchange, there will be substantial hadronic activity besides the two jets which are present in the hard matrix element. Thus, it is important not only to calculate the hard process, but to simulate the whole scattering. The event generator Herwig++ provides an excellent tool to study the remainders of the promising features of Hjj processes after hadronization. Comparisons of different observables will be given between the matrix element level and the event level.
