Event Generators for High-Energy Physics Experiments / Campbell, J.M. (Fermilab) ; Diefenthaler, M. (Jefferson Lab) ; Hobbs, T.J. (Fermilab ; IIT, Chicago) ; Höche, Stefan (Fermilab) ; Isaacson, Joshua (Fermilab) ; Kling, Felix (DESY) ; Mrenna, Stephen (Fermilab) ; Reuter, J. (DESY) ; Alioli, S. (Milan Bicocca U. ; INFN, Milan Bicocca) ; Andersen, J.R. (Durham U., IPPP) et al.
We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of active development, and opportunities for future improvements. [...]

Automation of One-Loop Calculations with GoSam: Present Status and Future Outlook / Cullen, Gavin (Edinburgh U.) ; Greiner, Nicolas (Illinois U., Urbana ; Munich, Max Planck Inst.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Luisoni, Gionata (Durham U.) ; Mastrolia, Pierpaolo (Munich, Max Planck Inst.) ; Ossola, Giovanni (New York City Coll. Tech. ; CUNY, Graduate School - U. Ctr.) ; Reiter, Thomas (Munich, Max Planck Inst.) ; Tramontano, Francesco (CERN)
In this presentation, we describe the GoSam (Golem/Samurai) framework for the automated computation of multi-particle scattering amplitudes at the one-loop level. The amplitudes are generated analytically in terms of Feynman diagrams, and can be evaluated using either D-dimensional integrand reduction or tensor decomposition. [...]

Automated One-Loop Calculations with GoSam / Cullen, Gavin (DESY, Zeuthen ; Edinburgh U.) ; Greiner, Nicolas (Illinois U., Urbana ; Munich, Max Planck Inst.) ; Heinrich, Gudrun (Munich, Max Planck Inst.) ; Luisoni, Gionata (Durham U., IPPP) ; Mastrolia, Pierpaolo (Padua U. ; INFM, Padua) ; Ossola, Giovanni (New York City Coll. Tech. ; CUNY, Graduate School - U. Ctr.) ; Reiter, Thomas (Munich, Max Planck Inst.) ; Tramontano, Francesco (CERN)
We present the program package GoSam which is designed for the automated calculation of one-loop amplitudes for multi-particle processes in renormalisable quantum field theories. The amplitudes, which are generated in terms of Feynman diagrams, can be reduced using either D-dimensional integrand-level decomposition or tensor reduction. [...]

Modern Feynman Diagrammatic One-Loop Calculations / Reiter, Thomas (NIKHEF, Amsterdam) ; Cullen, Gavin (Edinburgh U.) ; Greiner, Nicolas (Illinois U., Urbana) ; Guffanti, Alberto (Freiburg U.) ; Guillet, Jean-Philippe (Annecy, LAPTH) ; Heinrich, Gudrun (Durham U., IPPP) ; Karg, Stefan (Aachen, Tech. Hochsch.) ; Kauer, Nikolas (Royal Holloway, U. of London) ; Kleinschmidt, Tobias (Durham U., IPPP) ; Koch-Janusz, Maciej (NIKHEF, Amsterdam) et al.
In this talk we present techniques for calculating one-loop amplitudes for multi-leg processes using Feynman diagrammatic methods in a semi-algebraic context. Our approach combines the advantages of the different methods allowing for a fast evaluation of the amplitude while monitoring the numerical stability of the calculation. [...]

NLO QED Corrections to Hard-Bremsstrahlung Emission in Bhabha Scattering / Actis, Stefano (RWTH Aachen U.) ; Mastrolia, Pierpaolo (CERN) ; Ossola, Giovanni (New York City Coll. Tech.)
In this paper we present a numerical implementation of the one-loop QED corrections to the hard-bremsstrahlung process e- e+ \to e- e+ gamma. These corrections can be included in the Monte Carlo event generators employed for simulating Bhabha scattering events at low-energy high-luminosity electron-positron colliders. [...]
