CMS Open Data Workshop 2024

CERN IdeaSquare

Jul 29 - Aug 1, 2024

08:00 - 18:00 CEST

Instructors: Matt Bellis, Julie Hogan, Kati Lassila-Perini, Tom McCauley, Sezen Sekmen

Helpers: Xavier Tintin, Daniela Merizalde, David Mena

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. During the workshop, participants will learn how to analyze CMS Open Data in the afternoons, and will have the chance to build out their research projects with expert help during the "hackathon" sessions in the morning.

Who: This workshop is primarily aimed at students and scientists with prior knowledge of collider physics and a deep interest in learning the works and arts of conducting experimental analysis using CMS Open Data.

Where: Rte de Meyrin 372, 1217 Meyrin. Get directions with OpenStreetMap or Google Maps.

When: Jul 29 - Aug 1, 2024. 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.

Contact: Please email cms-dpoa-coordinators@cern.ch for more information.


Code of Conduct

All workshop participants are expected to follow the CERN Code of Conduct.
