Photon-photon physics may hold the key to many discoveries, whether these are new exotic mesons, ALPs, or precision effects beyond the Standard Model. It is important to assess and efficiently exploit the discovery potential of \(\gamma\gamma\) collisions at the existing and newly-built experimental facilities (MAMI, MESA, BESIII, LHC), along with the theoretical work on quantifying the QCD contribution.

At the Johannes Gutenberg University (JGU) Mainz, we have formed a close-knit team of researchers, ready to take on these tasks within the Research Unit FOR 5327. Our team has broad and complementary expertise in various aspects of photon-photon physics, both in theory and experiment.

By including international experts, this Research Unit 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 is composed of five interconnected projects that use the synergies between theoretical and experimental physics and will further strengthen the already close interactions between the phenomenology, lattice, and experimental groups.
