Description

There are a variety of interesting theoretical models that predict the signature known as Semivisible Jets. These are jets of hidden particles of which only a fraction decay visibly. Many of these models provide an elegant solution to open questions concerning the origin of dark matter and/or the problem of the apparent unnaturalness of the Standard Model. Due to the challenges of their experimental signatures, these classes of models are underdeveloped and poorly explored. Recent developments in reconstruction and identification techniques made it possible to probe such models at the Large Hadron Collider experiments.
This Workshop intends to foster the collaboration of the experimental and theory communities to establish a set of realistic benchmark models that will drive future search strategies. Theorists and experimentalists will work together in the period leading to the Workshop to focus on potentially interesting models. The outcome of these feasibility studies will inform and guide the workshop discussion. The Workshop will also feature talks from experts in Monte Carlo generators, QCD-related jet variables, and machine learning tools.

The outcome of the workshop studies and discussions will be summarised in a white paper.

The Workshop will be in hybrid mode: at the Hönggerberg campus of ETH Zürich and online via zoom:
