3 Flags to control anomalous couplings in KORALZ
Library of anomalous τ τ γ couplings for τ + τ − (nγ) Monte Carlo programs ABSTRACT We briefly describe a library that may be used with any e + e − → τ + τ − (nγ) Monte Carlo program to account for the effects of anomalous τ τ γ couplings. The implementation of this library in KORALZ version 4.04 is discussed.
متن کاملHERWIG 6 . 4 Release Note
A new release of the Monte Carlo program HERWIG (version 6.4) is now available. The main new features are: spin correlations between the production and decay of heavy fermions, i.e. top quarks, τ leptons and SUSY particles; polarization effects in SUSY production processes in lepton-lepton collisions; an interface to TAUOLA for τ decays; MSSM Higgs processes in lepton-lepton collisions.
متن کاملReplica Monte Carlo Simulation (revisited)
In 1986, Swendsen and Wang proposed a replica Monte Carlo algorithm for spin glasses [Phys. Rev. Lett. 57 (1986) 2607]. Two important ingredients are present, (1) the use of a collection of systems (replicas) at different of temperatures, but with the same random couplings, (2) defining and flipping clusters. Exchange of information between the systems is facilitated by fixing the τ spin (τ = σ...
متن کاملThe tauola-photos-F environment for the TAUOLA and PHOTOS packages, release II
We present the system for versioning two packages: the TAUOLA of τ -lepton decay and PHOTOS for radiative corrections in decays. The following features can be chosen in an automatic or semi-automatic way: (1) format of the common block HEPEVT; (2) version of the physics input (for TAUOLA): as published, as initialized by the CLEO collaboration, as initialized by the ALEPH collaboration (it is s...
متن کاملUHE and EHE neutrino induced taus inside the Earth
Tau neutrinos interacting inside the Earth produce τ leptons which thereafter can decay inside the atmosphere. The propagation of extremely energetic ντ ’s and τ ’s through the Earth is studied by means of a detailed Monte Carlo simulation, taking into account all major mechanisms of ντ interactions and τ energy loss as well as decay modes. The rates of τ ’s emerging from the Earth are determin...
