CMS Open Data Workshop

University of Notre Dame

28-30 July 2026

Instructors: Matt Bellis, Edgar Carrera, Claudia Constante, Julie Hogan, Clemens Lange, Kati Lassila-Perini, Thomas McCauley, Jorge Munoz, Jose Ochoa, Emily Rensch, Pablo Saiz, Katie Salvatore

General Information

Since 2014, the CMS Collaboration has pioneered the release of LHC research quality data for public use by making a significant amount of these data accessible through the CERN Open Data portal. In April 2024, the CMS Collaboration released the first batch of Run 2 data in the NanoAOD format. This workshop aims to bridge the technical gap that usually exists between the scientific creativity of an external analyst and the nuts-and-bolts details of a full analysis with CMS open data. All exercises will be hands-on and participants should be prepared to dive into the data right away. Before the workshop, participants should complete the software pre-exercises.

Who: This workshop is primarily aimed at high-school and secondary school teachers and college and university lecturers with a deep interest in learning the works and arts of conducting experimental analysis using CMS Open Data and bringing this knowledge into their classrooms and lecture halls.

Where: Room 202, Nieuwland Science Hall, Notre Dame, IN 46556 USA. Get directions with OpenStreetMap or Google Maps. See also the Campus Map.

When: 28-30 July 2026. Add to your Google Calendar.

Requirements: Participants must bring a laptop with a Mac, Linux, or Windows operating system (not a tablet, Chromebook, etc.) on which they have administrative privileges. They should have a working software container environment as listed in the pre-exercises section.

Accessibility: We are dedicated to providing a positive and accessible learning environment for all. Please notify the instructors in advance of the workshop if you require any accommodations or if there is anything we can do to make this workshop more accessible to you.
