CMS Open Data Workshop at WHEPP XVII, 2024

WHEPP XVII, IIT Gandhinagar

Jan 3-10, 2024

5:45 - 7:15 pm IST

Instructors: Julie Hogan, Kati Lassila-Perini, Matt Bellis

Student Facilitators: Aravind Sugunan, Ritik Saxena, Atul Jaiswal, Pruthvi Suryadevara, Mukund Shelake

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. At the end of 2021, the CMS Collaboration released the first batch of its Run 2 data. 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. Participants will begin by completing software setup exercises, and then the final four days of the workshop will focus on learning how to perform research-level analysis with CMS Open Data.

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: Gandhinagar. Get directions with OpenStreetMap or Google Maps.

When: Jan 3-10, 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 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.
