is a universal object-oriented neutrino MC generator supported and developed by an
international collaboration of scientists
whose expertise covers a very broad range of neutrino physics aspects, both phenomenological and experimental. GENIE is currently being used by
GENIE has many notable features:
An extensible, object-oriented core framework written in C++.
everages existing HEP software packages like
Abstract interfaces decouple neutrino interaction physics modeling from experiment specific inputs (flux, geometry navigation).
A highly portable XML format (the so-called “cross-section spline”) for specifying the event cross-sections and process types.
Easy detector geometry integration via
exactly compatible with
A flux driver capable of simulating neutrino beams in arbitrary functional forms in addition to sampling one-dimensional histograms or multi-dimensional ntuples.
A very broad energy coverage: GENIE strives to simulate all relevant interaction processes for any nucleus.
Reweighting machinery that is heavily used by experiments for systematic error estimation.
A strong connection to data: GENIE packages external data, and code for comparisons.
es for writing event records in a customizable ROOT format, along with a variety of built-in output formats. It is even able to mimic the output format of other, older generators (NeuGen, etc.).
A useful built-in library of physics models and a
robust configuration system that makes it simple to set up the equivalent of

utrino - nucleus generator.
Availability of generic event generation applications and of many experiment-specific event generation applications (NuMI experiments, T2K, SK) for the neutrino flux.
