The Workshop aims at bringing together theorists and experimentalists working on the phenomenology of the TeV colliders with an emphasis on the physics at the LHC. The 2019 session will concentrate on the results of the Run 2 and its consequences. The series gives as much attention to progress in new techniques for the simulation of Standard Model processes as well as to the latest developments concerning new mechanisms of symmetry breaking and the New Physics. Studies are conducted within working groups covering these various aspects of collider physics. In addition an inter-group dedicated to Tools and Monte Carlos is set up.
