The automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations
/ Alwall, J. (Taiwan, Natl. Taiwan U.) ; Frederix, R. (CERN) ; Frixione, S. (CERN) ; Hirschi, V. (SLAC) ; Maltoni, F. (Louvain U., CP3) ; Mattelaer, O. (Louvain U., CP3) ; Shao, H. -S. (Peking U. ; Peking U., SKLNPT) ; Stelzer, T. (Illinois U., Urbana) ; Torrielli, P. (Zurich U.) ; Zaro, M. (Paris U., IV ; Paris, LPTHE)
We discuss the theoretical bases that underpin the automation of the computations of tree-level and next-to-leading order cross sections, of their matching to parton shower simulations, and of the merging of matched samples that differ by light-parton multiplicities. We present a computer program, MadGraph5_aMC@NLO, capable of handling all these computations -- parton-level fixed order, shower-matched, merged -- in a unified framework whose defining features are flexibility, high level of parallelisation, and human intervention limited to input physics quantities.

Collider aspects of flavor physics at high Q
/ del Aguila, F. (Granada U.) ; Aguilar-Saavedra, J.A. (Granada U.) ; Allanach, B.C. (Cambridge U., DAMTP) ; Alwall, Johan (Louvain U.) ; Andreev, Yu. (Moscow, INR) ; Aristizabal Sierra, D. (Valencia U.) ; Bartl, A. (Vienna U.) ; Beccaria, M. (INFN, Lecce ; Salento U.) ; Bejar, S. (Barcelona, IFAE ; Barcelona, Autonoma U.) ; Benucci, L. (INFN, Pisa) et al.
This review presents flavour related issues in the production and decays of heavy states at LHC, both from the experimental side and from the theoretical side. We review top quark physics and discuss flavour aspects of several extensions of the Standard Model, such as supersymmetry, little Higgs model or models with extra dimensions. [...]

A Les Houches Interface for BSM Generators
/ Alwall, Johan (SLAC) ; Boos, E. (SINP, Moscow) ; Dudko, L. (SINP, Moscow) ; Gigg, M. (Durham U., IPPP) ; Herquet, M. (Louvain U., CP3) ; Pukhov, A. (Moscow State U.) ; Richardson, P. (Durham U., IPPP ; CERN) ; Sherstnev, A. (Cambridge U. ; SINP, Moscow) ; Skands, Peter Z. (CERN ; Fermilab)
We propose to combine and slightly extend two existing 'Les Houches Accords' to provide a simple generic interface between beyond-the-standard-model parton-level and event-level generators. [...]

Comparative study of various algorithms for the merging of parton showers and matrix elements in hadronic collisions
/ Alwall, Johan (SLAC) ; Hoche, Stefan (Durham U., IPPP) ; Krauss, F. (Durham U., IPPP) ; Lavesson, N. (Lund U.) ; Lonnblad, L. (Lund U.) ; Maltoni, F. (Louvain U., CP3) ; Mangano, M.L. (CERN) ; Moretti, M. (Ferrara U. ; INFN, Ferrara) ; Papadopoulos, C.G. (Democritos Nucl. Res. Ctr.) ; Piccinini, F. (INFN, Pavia) et al.
We compare different procedures for combining fixed-order tree-level matrix-element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW and MLM schemes using different matrix-element generators and different parton cascades.

A standard format for Les Houches Event Files
/ Alwall, Johan ; Ballestrero, A. ; Bartalini, P. ; Belov, S. ; Boos, E. ; Buckley, A. ; Butterworth, J.M. ; Dudko, L. ; Frixione, S. ; Garren, L. et al.
A standard file format is proposed to store process and event information, primarily output from parton-level event generators for further use by general-purpose ones. The information content is identical with what was already defined by the Les Houches Accord five years ago, but then in terms of Fortran commonblocks. [...]
