GENIE

GENIE is the world’s leading neutrino event generator, bridging theory and experiment in modern neutrino physics. It underpins data interpretation and exploitation across major experiments with cutting-edge physics models and advanced software tools. Liverpool leads GENIE’s development, driving innovation in interaction modelling, global fits, and community-wide software infrastructure.

GENIE is an international collaboration of conducting influential phenomenology research at the interface of nuclear and particle physics. It provides a bridge between theory and measurement, playing a central role in the interpretation of modern neutrino data.

GENIE plays a leading role in a) the development of a modern and universal event generator framework and tools in support of neutrino experiments, b) the consistent and efficient implementation of diverse physics models within a common platform, c) the development and characterisation of novel comprehensive physics models for the simulation of neutrino interactions, and d) the development of an advanced global analysis of neutrino scattering data. Beyond neutrino interactions, GENIE also supports event generation for scattering experiments using charged lepton probes, as well as simulation for several beyond-the-Standard-Model (BSM) channels probed at the Intensity Frontier and/or with large volume neutrino detectors. It maintains extensive curated archives of relevant neutrino, electron and hadron scattering data and corresponding data/MC comparison tools, as well as state-of-the-art tuning machinery. The GENIE collaboration maintains a large collection of open or closed-source software packages, in common use in the experimental neutrino physics community. Through the GENIE Incubator, the collaboration provides an open platform and central coordination of community-wide generator development efforts, with over a hundred of contributors over the past few years. GENIE’s impact is underscored by its primary publication [NIM A614 (2010) 87-104], among the top 50 most cited papers in neutrino physics.

The University of Liverpool plays a pivotal role in GENIE. Prof. Andreopoulos is the founder and spokesperson of the GENIE collaboration, while Dr. Roda serves both as an incoming Technical Coordinator and User Forum Coordinator. The Liverpool group focusses on developing and characterizing GENIE’s comprehensive models and on advancing the GENIE global analysis, integrating theoretical insights with all available measurements into predictive, semi-empirical descriptions of neutrino interactions. This effort led to definitive recent publications in the field, including PRD 104 (2021) 7, 072009, PRD 105 (2022) 1, 012009, PRD 106 (2022) 11, 112001, and PRD 110 (2024) 7, 072016. In addition, the group harbours unique expertise in several modelling areas, including neutrino-induced hadronization and BSM simulations.
