| Popis: |
We report on the SHERPA+OPENLOOPS framework for fully automated simulations of scattering processes at next to leading order. OPENLOOPS performs the fast evaluation of one loop matrix elements and is interfaced to the SHERPA Monte Carlo event generator. The framework is applied to ttbb production with massive b quarks matched to the SHERPA parton shower. The finite b quark mass allows us to extend the kinematics to collinear b quarks from g >bb splittings. We find that this splitting mechanism has a significant impact in the ttH(bb) signal region. Furthermore we address ttbar production in conjunction with up to two jets merged with the MEPSN LO method resulting in a unified description of top pair plus multi jet production. |
