We describe the Monte Carlo event generator for black hole production and decay in proton-proton collisions - QBH version 1.02. The generator implements a model for quantum black hole production and decay based on the conservation of local gauge symmetries and democratic decays. The code in written entirely in C++ and interfaces to the PYTHIA 8 Monte Carlo code for fragmentation and decays.

We describe the Fortran code CPsuperH2.0, which contains several improvements and extensions of its predecessor CPsuperH. It implements improved calculations of the Higgs-boson pole masses, notably a full treatment of the 4×4 neutral Higgs propagator matrix including the Goldstone boson and a more complete treatment of threshold effects in self-energies and Yukawa couplings, improved treatments of two-body Higgs decays, some important three-body decays, and two-loop Higgs-mediated contributions to electric dipole moments. CPsuperH2.0 also implements an integrated treatment of several B-meson observables, including the branching ratios of Bs→μ+μ−, Bd→τ+τ−, Bu→τν, B→Xsγ and the latter's CP-violating asymmetry ACP, and the supersymmetric contributions to the mass differences. These additions make CPsuperH2.0 an attractive integrated tool for analyzing supersymmetric CP and flavour physics as well as searches for new physics at high-energy colliders such as the Tevatron, LHC and linear colliders.1

The program is based on recent renormalization-group-improved diagrammatic calculations that include dominant higher-order logarithmic and threshold corrections, b-quark Yukawa-coupling resummation effects and improved treatment of Higgs-boson pole-mass shifts. The couplings of the Higgs bosons to the Standard Model gauge bosons and fermions, to their supersymmetric partners and all the trilinear and quartic Higgs-boson self-couplings are also calculated. The new implementations include a full treatment of the 4×4(2×2) neutral (charged) Higgs propagator matrix together with the center-of-mass dependent Higgs-boson couplings to gluons and photons, two-loop Higgs-mediated contributions to electric dipole moments, and an integrated treatment of several B-meson observables.Solution method: One-dimensional numerical integration for several Higgs-decay modes, iterative treatment of the threshold corrections and Higgs-boson pole masses, and the numerical diagonalization of the neutralino mass matrix.Reasons for new version: Mainly to provide a coherent numerical framework which calculates consistently observables for both low- and high-energy experiments.Summary of revisions: Improved treatment of Higgs-boson masses and propagators. Improved treatment of Higgs-boson couplings and decays. Higgs-mediated two-loop electric dipole moments. B-meson observables.Running time: Less than 0.1 seconds. 相似文献3.

Because of their narrow width, τ decays can be well separated from their production process. Only spin degrees of freedom connect these two parts of the physics process of interest for high energy collision experiments. In the following, we present a Monte Carlo algorithm which is based on that property. The interface supplements events generated by other programs, with τ decays. Effects of spin, including transverse degrees of freedom, genuine weak corrections or of new physics may be taken into account at the time when a τ decay is generated and written into an event record. The physics content of the C++ interface is already now richer than its FORTRAN predecessor.Program summaryProgram title: TAUOLA++, versions 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.0.6Catalogue identifier: AELH_v1_0Program summary URL: http://cpc.cs.qub.ac.uk/summaries/AELH_v1_0.htmlProgram obtainable from: CPC Program Library, Queen?s University, Belfast, N.
