Robust Independent Validation of Experiment and Theory: Rivet version 3

TL;DR

Rivet version 3 enhances a key analysis library for particle collision data, enabling more robust validation of experiments and theories through new features like systematic uncertainty handling and detector emulation.

Contribution

This paper introduces Rivet version 3 with new capabilities for systematic uncertainties, heavy-ion and ep physics, and detector emulation, improving analysis preservation and validation.

Findings

Enhanced propagation of MC systematic-uncertainty weights

Support for heavy-ion and ep physics analyses

Systems for detector emulation implemented

Abstract

First released in 2010, the Rivet library forms an important repository for analysis code, facilitating comparisons between measurements of the final state in particle collisions and theoretical calculations of those final states. We give an overview of Rivet's current design and implementation, its uptake for analysis preservation and physics results, and summarise recent developments including propagation of MC systematic-uncertainty weights, heavy-ion and $ep$ physics, and systems for detector emulation. In addition, we provide a short user guide that supplements and updates the Rivet user manual.
