Jan Hamann (Unknown)30/06/2008, 12:30In the field of cosmology, the analysis of observational data with Bayesian methods is wide-spread. Only fairly recently it was suggested to apply these methods also to particle physics, to constrain the free parameters of supersymmetric models such as the CMSSM. The technical challenge of these analyses lies in the need to accurately sample a multi-dimensional parameter space in a reasonable...Go to contribution page

Claude Duhr (UCL)30/06/2008, 16:00The hunt for new physics at the LHC will bring up new challenges on both the theoretical and experimental side. Many tools, symbolical and numerical, are available nowadays to facilitate the communication between theorists and experimentalists involved in this hunt. However, the implementation of new physics models into the existing tools is a rather tedious work. I present a new tool called...Go to contribution page

Neil Christensen30/06/2008, 16:25As the LHC turns on, and our theoretical models prepare to confront data, we need to be prepared to implement various models in monte carlo event generators for comparison. There is a large number of monte carlo generators on the market including CalcHEP/CompHEP, MadGraph, Sherpa, Herwig, Whizard and others. Each of these tools has different strengths and weaknesses and so it would be ideal if...Go to contribution page

Andrey Semenov (JINR)30/06/2008, 17:00The LanHEP program for Feynman rules generation is presented. It reads the Lagrangian written in the compact form close to one used in publications. It means that Lagrangian terms can be written with summation over indices of broken symmetries and using special symbols for complicated expressions, such as covariant derivative and strength tensor for gauge fields. The output is Feynman rules in...Go to contribution page

Dr Oliver Brein (IPPP, Durham)01/07/2008, 12:00From the Higgs search at LEP and the Tevatron, limits on topological cross sections, which can be applied to a large class of models, have been derived or, in the case of the Tevatron, are still updated. Developed in collaboration with P. Bechtle, S. Heinemeyer, G. Weiglein, K. Williams, our code can decide for models with an arbitrary number of neutral Higgs bosons, with given deviations from...Go to contribution page

Dr Henning Flaecher (Royal Holloway, University of London)01/07/2008, 12:35Already today, low-energy data from flavour physics experiments, high precision electroweak observables as well as astrophysical data impose strong constraints on many new physics (NP) scenarios. In order to quantify the agreement of a particular NP model with the existing experimental measurements, a consistent set of theory predictions has to be provided. A common "MasterCode" to combine the...Go to contribution page

Dr Tania Robens (RWTH Aachen, Institut fuer Theoretische Physik E)02/07/2008, 11:35We present an extension of the Monte Carlo Event Generator Whizard which includes chargino production at the ILC at NLO. We include photons using both a fixed order and a resummation approach. While the fixed order approach suffers from negative event weights, the resummation method solves this problem and automatically includes leading higher order corrections. We present results for cross...Go to contribution page

Gideon Bella (High Energy Physics Department)02/07/2008, 16:30A detailed study of the di-boson Monte Carlo programs Pythia, MC@NLO and the program of Baur, Han and Ohnemus (BHO) is performed. None of these programs cover all aspects of di-boson production. The BHO code is used to produce event weights emulating anomalous triple gauge couplings in Pythia and MC@NLO events. In the same way, boson spin information which is missing for most di-boson channels...Go to contribution page
