“…As these new generators evolve and undergo extensive testing and validation, they are expected to enter the production shortly and eventually supersede their FORTRAN predecessors. Some production was also done with MadGraph [37] (vector boson scattering), CHARYBDIS [38] (black hole event generation), and CompHep [39,40] (specific exotic physics models). Discussion of the generation of cavern background, beam halo, and beam gas events follow in Sects.…”

The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for largescale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the AT-LAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.

A search for microscopic black holes in pp collisions at a center-of-mass energy of 7 TeV is presented. The data sample corresponds to an integrated luminosity of 4.7 fb −1 recorded by the CMS experiment at the LHC in 2011. Events with large total transverse energy have been analyzed for the presence of multiple energetic jets, leptons, and photons, which are typical signals of evaporating semiclassical and quantum black holes, and string balls. Agreement with the expected standard model backgrounds, which are dominated by QCD multijet production, has been observed for various combined multiplicities of jets and other reconstructed objects in the final state. Model-independent limits are set on new physics processes producing high-multiplicity, energetic final states. In addition, new model-specific indicative limits are set excluding semiclassical and quantum black holes with masses below 3.8 to 5.3 TeV and string balls with masses below 4.6 to 4.8 TeV . The analysis has a substantially increased sensitivity compared to previous searches.

“…Of course the energy requirement for BH pair production would yield an additional suppression factor and its proper consideration requires a Monte Carlo simulation. Therefore, we strongly recommend to include in future versions of the BH event generators charybdis [66] and catfish [67] a detailed treatment of production and evaporation of near-extremal supersymmetric BHs.…”
