Description
The axion particle discovery could answer the big CP problem as it is hypothetically predicted. Hence A study on the exotic decay of the Higgs boson to two Axion Like Particles (ALPs), which in turn decay to two photons, was carried out. This analysis covers the mass range of ALPs between 100 MeV and 60 GeV and ALPs-photon couplings C$_{a\gamma\gamma}$ of 10$^{-5}$ to 1, a region that includes signatures with significantly displaced vertices and highly collinear photons, which present the challenges of this analysis. No significant deviation from the SM expectations has been found, excluding a large parameter space of models that could have explained the (g - 2)$_\mu$ discrepancy.
