Last week the LHC Physics Center at Fermilab hosted a two-day workshop focusing on the future of jet substructure algorithms and their use in physics analyses. The workshop was organized by Gabriele Benelli, James Dolen, Robin Erbacher (co-chair), Julie Hogan, Christine McLean, Marc Osherson, Alexx Perloff, Justin Pilot (co-chair), Rizki Syarif, Nhan Tran and Caterina Vernieri.

The first day brought experimentalists and theorists together to discuss the latest developments in the field of jet substructure and to plan experimental measurements that can provide important feedback to the theory community. More than 50 participants discussed effects such as parton shower modeling, pileup mitigation methods, and their impact on substructure algorithm performance in data and simulation.

During the second day of the workshop, members of the CMS collaboration took stock of the current efforts for substructure validation and application in their analyses gearing towards the Moriond conference, including the performance and optimization of triggers and algorithms, background methods and jet calibrations. There were also discussions about plans for future studies of new substructure algorithms and measurements using CMS data sets.
