Abstract: 

The Large Hadron Collider (LHC), as the well-known energy frontier by colliding quarks and gluons, is also a powerful light-light 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. I will introduce an 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. In the second part of my talk, I will pick up a particular example on the light-by-light scattering process, and will discuss the precision SM predictions and its constraints on the hypothetical axion-like and graviton-like particles.
