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. At the end of 2021, the CMS Collaboration released the first batch of its Run 2 data. This workshop is a fourth of a series that started in 2020 and it 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. A set of pre-exercises and assignments are provided and required for participants so that they can make the most of the workshop. Time will also be spent brainstorming with attendees about how the entire process of accessing and analyzing the data could be made more useful for the broader HEP community.
Please visit the official Indico site for the workshop.
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. </strong>
Where: Fermilab, Wilson Hall. Get directions with OpenStreetMap or Google Maps.
When: July 11-14, 2023. Add to your Google Calendar. [US Central Daylight Time (CDT)]
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 virtual machine or Docker 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-opendata-workshop-organizers@cern.ch for more information.
All workshop participants are expected to follow the CERN Code of Conduct.
