Future colliders

• Roberto Franceschini (Rome 3 U.)

In this talk I will review the motivation for further exploration of physics at the shortest distances. I will review the role that particle colliders can play in future advances on the open issues of the Standard Model of particle physics. I will also briefly introduce the collider projects currently under discussion to push the energy frontier after the High- Luminosity LHC and the highlights of the physics that can be carried out at each machine.
