Jet substructure techniques are now routinely used in collider phenomenology. This specialised workshop evolves around a recent tool called the Lund Jet Plane(s). The main idea is to use the Cambridge/Aachen clustering technique (i.e. a roughly angular-ordered clustering tree) to associate a kinematic structure, akin to the Lund planes used in resummations and in Monte Carlo generators, to a high-energy jet. This structure can then be used in a wide range of applications. The goal of this workshop is to provide a theoretical and experimental overview of these applications and their connections with other tools in the field. A special emphasis will be put on recent developments and on discussions of future potential directions. This includes the following list of topics:
The workshop will consist of afternoon talks. One of the key aspect of the workshop will be to leave time for common discussions and work between theorists and experimentalists.
