Description
Abstract: The LHC, as the well-known energy frontier by colliding quarks and gluons, is also a powerful photon-photon collider at center-of-mass energies never reached before. In this talk, I will review the studies of the exclusive photon-photon processes in ultraperipheral collisions mainly from a theoretical perspective. I will first introduce a new automated Monte Carlo tool called gamma-UPC that enables the event generation of arbitrary exclusive final states via photon-photon fusion in ultraperipheral collisions of protons and/or nuclei, which is of relevance for novel SM measurements and BSM searches. As an example of SM measurements, I will talk about the light-by-light scattering process. I will finally take the hypothetical graviton-like particles as an instance of searching for BSM particles.
