== MadWeight == Given a sample of experimental events and a set of theoretical models, the matrix element method is a procedure to select the most plausible model that governs the production of these events. For each event, we determine a specific weight that is the convolution of the squared matrix element and the resolution function. Although the definition of this weight is very simple, its numerical estimation is not straightforward. The shape of the transfer function together with the behavior of the squared matrix element require to use a specific parametrization for the phase-space integration. '''MadWeight''' is a phase-space generator that is designed for the computation of the weights. === Info === * [wiki:MatrixElement Description of the matrix element method] * [wiki:MadWeightPresentation Seminar/procedings/article presenting MadWeight] * TransferFunction : subjects related to transfer functions (standing from "what is a transfer function" to "how to implement a new TF in MadWeight") * AcceptanceTerm: What is the acceptance term and how to compute it. * StartingMadWeight: what is required in order to launch MadWeight * MadWeightOption: description of all options you can use in a MadWeight run * MadWeightFAQ: frequent user questions/errors * MadWeightAnalyzer : description of the program that produces the process-dependent phase-space generator * MadWeightTool : different script devellop by some MadWeight user. * [http://madgraph.phys.ucl.ac.be/Downloads/MW_UpdateNote.txt Update Notes]: Update Note of MadWeight * [https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MW_development MW_development ] %ICON{key}% :restricted area * DifferentialWeight %ICON{key}%: Computation of differential weight (in progress) === People === 1.
