Photon-photon physics may hold the key to many discoveries, whether these are new exotic mesons, ALPs, or precision effects beyond the SM. It is important to assess and efficiently exploit the discovery potential of \(\gamma\gamma\) collisions at the existing and newly-built experimental facilities, along with the theoretical work on quantifying the QCD contribution.
A close-knit team of researchers at Johannes Gutenberg University (JGU) Mainz are currently taking on these tasks. Our team has broad and complementary expertise in various aspects of photon-photon physics, both in theory and experiment. By including international experts, the FOR 5327 will expand its expertise and advance the understanding of \(\gamma\gamma\) interactions as a precision and discovery tool, and thereby have a decisive impact on hadron and particle physics.
The Research Unit includes five interconnected projects:
