KROWIG Version 1.0: Interfacing KRONOS and HERWIG or Higher Order Electromagnetic Radiative Corrections at HERA with Hadronic Final States

This manual describes version 1.0 of the Monte Carlo event generator KROWIG for deep inelastic lepton hadron scattering at HERA. KROWIG combines the implementation of QED radiative corrections in KRONOS with the QCD parton showers and cluster fragmentation of HERWIG.Comment: 22 pages, DESY 92-09

Automated Calculation and Simulation Systems

I briefly summarize the parallel sessions on Automated Calculation and Simulation Systems for high energy particle physics phenomenology at ACAT 2002 (Moscow State University, June 2002) and present a short overview over the current status of the field and try to identify the important trends.Comment: 4 pages, LaTeX, to appear in the proceedings of ACAT 200

Probing the Noncommutative Standard Model at Hadron Colliders

We study collider signals for the noncommutative extension of the standard model using the Seiberg-Witten maps for SU(3)_C x SU(2)_L x U(1)_Y to first order in the noncommutativity parameters theta_munu. In particular, we investigate the ensitivity of Z-gamma-production at the Tevatron and the LHC to the components of theta_munu. We discuss the range of validity of this approximation and estimate exclusion limits from a Monte Carlo simulation.Comment: 18 pages LaTeX, 23 figures. Slightly expanded introduction and additional references. Accepted for publication in Physical Review

Production of Dark Matter in Warped Higgsless Models with Composite Sector Supersymmetry

We explore the LHC phenomenology of an extension of warped higgsless models. The model is supersymmetric in the bulk and on the IR brane as introduced in [arXiv:0805.1379], corresponding to an emergence of a supersymmetric spectrum in the composite sector of the higgsless model. In particular, the lightest neutralino is rendered stable by an R parity and serves as a realistic cold dark matter candidate. The observation of missing energy signals at the LHC from LSP and NLSP production in association with third generation quarks is discussed based on simulations using WHIZARD.Comment: 21 pages, LaTeX, figures include

Environment

Many environmental problems are large scale in terms of geographical units and long-term with regard to time. We therefore find a coincidence of different causes and impacts that qualify the interplay between humans and nature as highly uncertain (“transparency challenge”). In consequence we see a need for innovative analytical methods and modelling approaches to supplement the traditional monitoring-based approach in environmental policy. This should allow capturing different degrees of uncertainty which in general is out of power of any monitoring activity. Moreover, with regard to the design of monitoring approaches it requires collecting and connecting data from different fields of social activities in regard of a divergence of natural and social systems’ boundaries. This requires the provision of sufficient, frequently huge data sets (“availability challenge”) that need to fit with each other (“compatibility challenge”). Even if these challenges are met data processing remains a very complex and time-consuming task which should be supported by a user-friendly infrastructure. We here see a comparative advantage in using the GIS technology and a nested structure for data provision supporting the up and down scaling of information and the access of data from different perspectives (“connectivity challenge”) - a polluters, a victims and a regulators point of view.Coincidence of causes and impacts, transparency challenge, availability challenge, compatibility challenge, connectivity challenge, GIS technology, nested structure of data provision
