The CMS Data Analysis Schools (CMSDAS)


CMSDAS@LPC2023


More information and Registration at the CMSDAS@LPC2023 indico page

CMSDAS is designed to help CMS physicists from across the collaboration to learn, or to learn more, about CMS analysis and thereby to participate in significant ways in any physics analysis including future discoveries. It enables physicists beginning analysis to easily join an ongoing analysis in a productive way. Since 2012, our first global year, schools have been held at Fermilab, Pisa, Taipei, DESY, Kolkata, Bari and Korea and over 1000 CMS students have now participated in the program. The format for each CMSDAS is very similar and some of the same facilitators attend each school.

A few key components of CMSDAS are required “homework”, assigned to registrants prior to attending the school and during the workshop sessions, emphasizing "hands-on" work with CMS data. Each school starts with a morning devoted to informational plenary talks followed by the execution of a series of short and long exercises, the essential features of the school.

Prior to the school, attendees are required to complete a list of pre-exercises in order to be able to tackle more realistic problems at the tutorial sessions. They include, for example, introducing CMSSW, finding datasets, fitting, etc. which ensures a fast start at the event.

Note: All attendees need to have accounts both at CERN and FNAL, as well as a CMS grid certificate. Part of the pre-exercises are designed to make sure this is the case. Due to the intensive hands-on nature of the school, an attendee without this requirement would be in serious disadvantage. Once a user has CERN accounts, getting accounts at Fermilab can take up to six weeks (including site access), this is why this is required prior to attending school. Account requests CAN be made prior to CMSDAS registration.

The short exercises (several hours duration) cover all of the objects from jets to muons and many techniques from event generators to setting upper limits. They occur during the first half of the school followed by the long exercises during the second half. Long exercises are devoted to performing detailed physics measurements using CMS data in a 2.5-day intensive period by focused teams of about 5-10 students. Both the short and long exercises are designed and facilitated by teams of 5-8 CMS experts called facilitators. Some long exercises go beyond the current state of the art of the corresponding CMS analysis. This provides opportunities to get plugged into a CMS measurement through a long exercise at the school and become a part of the CMS measurement team on the paper. Attendance to both short and long exercises is required to fully participate in the team effort of CMSDAS.
