The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

CHARYBDIS is an event generator which simulates the production and decay of miniature black holes at hadronic colliders as might be possible in certain extra dimension models. It interfaces via the Les Houches accord to general purpose Monte Carlo programs like HERWIG and PYTHIA which then perform the parton evolution and hadronization. The event generator includes the extra-dimensional `grey-body' effects as well as the change in the temperature of the black hole as the decay progresses. Various options for modelling the Planck-scale terminal decay are provided.

Original abstract

CHARYBDIS is an event generator which simulates the production and decay of miniature black holes at hadronic colliders as might be possible in certain extra dimension models. It interfaces via the Les Houches accord to general purpose Monte Carlo programs like HERWIG and PYTHIA which then perform the parton evolution and hadronization. The event generator includes the extra-dimensional `grey-body' effects as well as the change in the temperature of the black hole as the decay progresses. Various options for modelling the Planck-scale terminal decay are provided.

No microscopic black holes appeared in 35 inverse picobarns of 7 TeV CMS data, giving 95% confidence lower limits of 3.5 to 4.5 TeV on the minimum black hole mass in large-extra-dimension models.
Systematic event generator tuning for the LHC

A polynomial surrogate of per-bin generator response turns an intractable tuning problem into a fast numerical minimisation, yielding Pythia 6 parameter sets that fit LEP/SLD and Tevatron data better than the defaults.
