In conjunction with MC4BSM, we will also hold a HEFTI workshop which focuses on collider signals of jets/leptons plus missing energy. The purpose is to discuss the strategies to search for new physics with missing energy signals and how to identify the new physics if such experimental signals are discovered. We hope the workshop can bring the experimentalists and theorists working in this area together to develop the best approaches to these problems.

To contact the organizers, please send email to
mc4bsm@particle.physics.ucdavis.edu.

Organizing committee: Hsin-Chia Cheng, Max Chertok, John Conway, Robin Erbacher, Christophe Grojean, Jack Gunion, Markus Luty, Konstantin Matchev, Steve Mrenna, Maxim Perelstein, Peter Skands, John Terning.
