Description
Axion-Like particles (ALPs) are pseudoscalar neutral particles that are predicted by many New Physics theories. The GeV mass range is interesting for several reasons: the constraints in parameter space are weaker, the flavour structure of the couplings to SM fermions plays an important role, and it can be explored by different experiments such as BESIII, Belle II and LHCb. But there is also an important theoretical challenge in the description of ALP processes involving light mesons. In this talk, I will present the code ALP-aca (ALP automatic computing algorithm) that we have developed in order to study the phenomenology of GeV ALPs, and discuss some application in ALPs produced in flavour-changing meson decays, quarkonia decays and proton collisions.
