Description

Welcome to Tools 2012!

NEWS! With the support of the Oskar Klein Centre, Stockholm University, The Swedish Research Council, Enigmass and LAPTH we are happy to announce that we have decided to reduce the workshop fee to 0 SEK.

The program for the workshop is available by the link Timetable in the left-hand menu. You can also click here for a direct link.

The aim of the workshop is to review the main calculational tools, such as generators and Monte Carlos, for searches of the New Physics at present and future colliders as well as in non-collider physics experiments such as dark-matter searches. Issues and codes pertaining to the background will also be covered. Ultimately, the goal is a first comparison of all such tools with real data from the LHC and elsewhere.
The workshop is structured around (i) a series of talks (with and without software demo), (ii) tutorials, and (iii) round-table discussions. The talks give an overview of available tools, the tutorials convey hands-on information of the main packages, and in the round-table discussions we hope to discuss how the existing programs could be improved, how to incorporate different existing constraints, how to best present future data, and how modules from different codes could be sewn together and interchanged.
We plan to have the following themes:

  • Particle Physics Phenomenology
  • Scanning Tools
  • Event generators and detector simulators
  • Rare decays and other constraints
  • Astroparticle Physics Phenomenology

The program will consist of both invited talks, contributed talks, tutorials and round table discussions.

        SARAH: Spectrum-Generator-Generator and more 30m
        SARAH is a Mathematica package optimized for the fast and exhaustive analysis of supersymmetric models. It has been designed to handle every N = 1 SUSY theory with an arbitrary direct product of SU (n) and/or U (1) factors as gauge group. The chiral superfields can transform under arbitrary, irreducible representations with regard to this gauge group, and all possible renormalizable superpotential terms are supported. New models can be implemented in an easy and straight-forward manner and SARAH can create as output model files for FeynArts/FormCalc, CalcHep/CompHep, WHIZARD and Madgraph. In addition, SARAH can be used as spectrum-generator-generatore because it writes modules for SPheno to create a full-fledged spectrum calculator for new models. The features of these spectrum generators include a precise mass spectrum calculation using two-loop RGEs and full one-loop corrections, two and three body decays of SUSY and Higgs particles as well as the calculation of electroweak precision observables. Furthermore, SARAH is the heart of the recently presented 'SUSY toolbox' which provides an environment for the study of MSSM extensions using SPheno, CalcHep/MicrOmegas, WHIZARD and Higgsbounds. This framework combines the different outputs of SARAH to provide a closed tool-chain from model building to phenomenology.

        FeynRules 30m
        In this talk, I would like to present FeynRules, a Mathematica® package that allows the calculation of Feynman rules in momentum space for any quantum field theory physics model, starting from the model Lagrangian. The Feynman rules calculated by the code can then be used to implement the new physics model into other existing tools, such as Monte Carlo generators, via a set of dedicated interfaces. A special emphasis will be put on the new features and future development plans: - The Universal FeynRules Output (UFO) - The superspace module - Supersymmetric RGE's and interface with the SuSpect-3 program - Spin 3/2 physics - Automatic model file generation - Web-based model validaltion

        SPheno 3.1: extensions including flavour, CP-phases and models beyond the MSSM 40m
        We describe recent extensions of the program SPheno including flavour aspects, CP-phases, R-parity violation and low energy observables. In case of flavour mixing all masses of supersymmetric particles are calculated including the complete flavour structure and all possible CP-phases at the 1-loop level. We give details on implemented seesaw models, low energy observables and the corresponding extension of the SUSY Les Houches Accord. Moreover, we comment on the possiblities to include MSSM extensions in SPheno.

        We present a Fortran code which calculates the production cross section for the (lightest) Higgs boson in the SM and MSSM resulting from gluon fusion and bottom-quark annihilation. Differential and total cross sections are obtained at NLO in gluon fusion, taking into account the full contribution from the third generation of quarks and squarks in the MSSM. Inclusive weighted results up to NNLO from gluon and/or bottom-quark fusion can be added. In addition to the features of this program, the talk discusses the impact of different renormalization schemes for the squark sector in the MSSM.

        HiggsBounds and the HiggsSignals extension: status and prospects 40m
        We present the current status of the public Fortran code HiggsBounds. The program confronts arbitrary Higgs sectors with the exclusion limits from direct Higgs searches at LEP, Tevatron and the LHC. We demonstrate a recent improvement of the model likeness criteria, which allows in particular Higgs searches combining different channels to be applied to a wider class of models. Furthermore, we shall discuss some ideas for a planned code extension (HiggsSignals), which tests the agreement of a model with possible future observations of a Higgs signal at the LHC.

        CalcHEP and HEPMDB: a practical introduction 40m
        The practical introduction into CalcHEP package and High Energy Physics Model database will be given together with the short tutorial. CalcHEP is a powerful tool for theoretical, phenomenological and experimental studies in High Energy Physics (HEP). CalcHEP allows users to automate the calculations and studies starting from the introduction of any user-defined model and ending by the realistic event simulation, kinematical distributions and analysis. In its present status CalcHEP can be considered is a ready setup for study of LHC physics within Standard Model and Beyond. On the other hand HEPMDB is a convenient centralized storage environment for HEP models, and can accommodate, via web interface to the HPC cluster, the validation of models, evaluation of LHC predictions and event generation-simulation chain. The ultimate goal of HEPMDB is perform an effective LHC data interpretation isolating the most successful theory for explaining the LHC observations.

        CLUMPY: A code for gamma-ray signals from dark matter structures 30m
        In this talk, I will give an overview of the main properties and functionalities of the CLUMPY code. CLUMPY performs a semi-analytical calculation of the γ-ray flux astrophysical J-factor from dark matter annihilation/decay in the Galaxy, including dark matter substructures. The code can be used in three modes: i) to draw skymaps from the Galactic smooth component and/or the substructure contributions, ii) to calculate the flux from a specific halo (that is not the Galactic halo, e.g. dwarf spheroidal galaxies) or iii) to perform simple statistical operations from a list of allowed DM profiles for a given object.

In order to show the model-independence of the AMIDAS package, a comparison between the blindly reconstructed results and the original (non-standard) input setup for generating both the WIMP signals as well as a small amount of artificially added background events will also be given.

        Constraints on Dark Matter and SUSY from global fits including LHC and direct detection data 30m
        The dark matter particle is currently being searched for with several observational channels, including the LHC and direct detection experiments. These experiments already place constraints on a number of theoretical WIMP models, including weak-scale supersymmetry (SUSY). In this talk, I will present constraints on the parameters of the constrained Minimal Supersymmetric Standard Model (cMSSM) obtained from global fits including recent data from the LHC and the XENON100 direct detection experiment.

        Neutrino telescope likelihood extensions in DarkSUSY 30m
        I will discuss the new neutrino telescope likelihood routines in DarkSUSY. These are based on a fast method for including event-level IceCube data in likelihood calculations, and are optimised for global-fit type parameter explorations of theories for new physics. The likelihood construction is not at all specific to SUSY, and includes both angular and spectral information about neutrino events, as well as their total number. I'll also discuss a corresponding measure for simple model exclusion, which can be used for single models without reference to the rest of a parameter space. I'll illustrate the use of the new routines with a number of examples from the MSSM, and show that including spectral information significantly improves model reconstructions.

        Fast Approximation of Supersymmetry Event Rates Beyond the CMSSM 40m
        Now that predictions of supersymmetric models can finally be compared to LHC data, it is important to have a means of quickly evaluating signal rates for parameter points during scans without having to generate and analyze full Monte Carlo simulations. We have written C++ code (LHC-FASER) which quickly estimates the event rates that would be seen at LHC, taking into account production cross-sections, branching ratios, and the effect of kinematic cuts, and does not rely on any particular SUSY-breaking scheme or mass hierarchy. This can be of particular use to fitting codes, especially since the lack of observation of sparticles thus far implies that event rates may be the only measurable observable available for the foreseeable future. The new version of LHC- FASER has a much larger, updated signal set.

        MadAnalysis 5, a user-friendly framework for collider phenomenology 40m
        We present MadAnalysis 5, a new framework for phenomenological inves- tigations at particle colliders. Based on a C++ kernel, this program allows to efficiently perform, in a straightforward and user-friendly fashion, sophis- ticated physics analyses of event files such as those generated by a large class of Monte Carlo event generators. MadAnalysis 5 comes with two modes of running. The first one, easier to handle, uses the strengths of a powerful Python interface in order to implement the analysis by the mean of a set of intuitive commands. The second one requires to implement the analysis in the C++ programming language, directly within the core of the anal- ysis framework. This opens unlimited possibilities concerning the level of complexity which can be reached by the analysis, being only limited by the programming skills and the originality of the user.

        Global Charge Asymmetry: a New Method for Indirect Mass Constraints at the LHC 30m
        Contrarily to most of the previous colliders, the initial state at the LHC is charge asymmetric. This property has been measured on the W process by the ATLAS and the CMS collaborations using their 2010 datasets. We propose a new method to use the global charge asymmetry of a production process to constrain the mass of its final state. We'll illustrate this method using particle level MC samples run through a fast simulation of an LHC detector on the W->l+nu process. In particular, we'll propagate separately the theoretical and the experimental uncertainties in order to estimate the mass resolution of our method. The application of this new method can be interesting to obtain further constraints in some BSM searches as we'll briefly illsutrate.

        Constrained Supersymmetry after two years of LHC data: a global view with Fittino 30m
        We perform global fits to the parameters of the Constrained Minimal Supersymmetric Standard Model (CMSSM) and to a variant with non-universal Higgs masses (NUHM1), taking into account the current LHC exclusions from searches in jets plus missing transverse energy signatures with about 5/fb integrated luminosity. We include the recent LHCb upper bound on the branching ratio Bs->mu+mu-. Also, constraints from and implications for direct and indirect dark matter searches are discussed. The minimum of the CMSSM fit prefers a light Higgs boson just above the experimentally excluded mass. A potential SM-like Higgs boson with mass around 126GeV can barely be accommodated. Values for Bs->mu+mu- just around the Standard Model prediction are naturally expected in the best fit region. The most-preferred region is not yet affected by limits on direct WIMP searches, but the next generation of experiments will probe this region. Finally, we consider the fine-tuning implications of our best fit regions.

        Framework for precision calculations in the NMSSM 30m
        We present a framework for precision calculations and numerical studies in the NMSSM. As a first example, we study the decay of a NMSSM Higgs boson into two photons and show that the interpretation of the excess recently observed in the Higgs searches at the LHC in terms of a 125 GeV Higgs with an enhanced gamma gamma rate would be compatible with the lightest CP-even Higgs in the NMSSM. As another application of the new framework we present the theoretical prediction of the W boson mass in the NMSSM and discuss the impact of LHC Higgs and SUSY searches on MW.
