ALPs up to the QCD scale and the true muonium

Axion like particles (ALPs) with coupling to photons or gluons have long been postulated as extension to the Standard Model. In this talk we explore different probes of ALPs at different energy scales up to the QCD scale. We consider ALPs at photon beam experiments and at superconducting radiofrequency cavities. In addition, we will discuss the prospects for discovering the true muonium at the LHCb experiment.
