KAMPAI - Kaonic, Antiprotonic, Muonic, Pionic and “onia” exotic Atoms: Interchanging knowledge and recent results 

Kaonic, antiprotonic, muonic and pionic atoms, as well as the so-called “onia”, are exotic systems where one or more sub-atomic particles are replaced by a different particle of identical charge. In particular kaons, pions or antiprotons replacing one of the orbital electrons are used to form hadronic atoms, while a muon forms a leptonic exotic atom. Finally, in a “hydrogen-like” configuration, a bound pair of a particle and its antiparticle or of two leptons represents an exotic system called onium; some of these states, like muonium, positronium and pionium, have been already experimentally observed but others may exist; their observation could enable important tests for both QCD and QED. All these exotic atoms represent unique tools for testing the foundation of electromagnetic, strong and even gravitational interactions. It is thus the right time for discussing synergy and exchanging information between the physics communities involved in exotic atoms studies.
