This workshop will bring together experimentalists and theorists exploring exotic atoms as precision laboratories for fundamental physics. Covering a broad spectrum of systems, from hadronic atoms, such as kaonic and pionic atoms, to leptonic bound states like positronium, the workshop will highlight their complementary roles in probing the strong and electromagnetic interactions.
A central focus will be on recent experimental advances, including high-precision spectroscopy of kaonic atoms within SIDDHARTA-2 and novel studies of positronium with dedicated facilities such as J-PET. These efforts provide unique access to low-energy QCD in the strangeness sector, stringent tests of bound-state QED, and new opportunities to investigate discrete symmetries.
The workshop will also address ongoing and future programs at leading international infrastructures, including DAFNE, J-PARC, and CERN, alongside progress in theoretical frameworks such as effective field theories, lattice QCD, and precision QED calculations.
By bridging different communities, the workshop aims to explore how exotic atoms can constrain fundamental interactions and open new windows on physics beyond the Standard Model. It will foster discussions on key open questions, future experimental strategies, and emerging interdisciplinary connections.
Note: the workshop will be in mixed modality; in presence and online
