The LHC as a photon collider: casting light on new phenomena
Helmholtz Young Investigator Group of Lydia Beresford (2022-2027)
The Large Hadron Collider (LHC) is the highest energy hadron collider in the world. It has enabled important insights into the nature of elementary particles. Almost all LHC researchers study these hadron collisions. However, the focus of this Young Investigator Group is on using the LHC in a novel way: as the world’s highest energy photon collider. Photon collisions occur when the electromagnetic fields surrounding LHC protons interact. This opens a new kinematic regime for laboratory photon collisions, thereby providing a promising route to discovering new phenomena which could solve some of the most fundamental questions in physics.
With my group we will search for dark matter using LHC photon collisions and will pioneer the use of novel forward proton detectors. These detectors help us to identify photon collisions and provide unique information about them. This new approach will enable us to search for dark matter particles in well-motivated, unexplored regions. We will also perform new measurements of photon interactions. By measuring the tau lepton magnetic moment (“g-2”) to world-leading precision we will test fundamental assumptions of the Standard Model. This could lead to a new understanding of the fundamental particles which make up our Universe.
