Concepts

These notebooks introduce a variety of concepts in High Energy Particle physics. They are intended to provide both a conceptual introduction and some real examples of how to study the concepts with the ATLAS Open Data.

Accessing Metadata NEW​

This notebook introduces the atlasopenmagic package, which is used throughout these notebooks for environment setup and data access. It introduces the concept of metadata, explains what metadata are available for the samples that have been provided, and introduces the use of a handful of convenient search functions to identify samples that might be of interest based on their metadata.

Detector Acceptance and Efficiency NEW​

This notebook introduces the concepts of detector acceptance and efficiencies, used to understand the response of the detector to different types of events. Using the 2025 release of ATLAS Open Data, we guide you through a practical example of how to calculate acceptance and efficiency, and show you how these concepts are used in real physics analyses.

Systematic Uncertainties NEW​

This notebook introduces the concept of systematic uncertainties, providing a small variety of examples of uncertainties that you might run into while using the ATLAS Open Data. There is both a pedantic introduction and a demonstration of the calculation of uncertainties using the Open Data.
