High-energy muon beams can emit collinear photons, leading to the production of multi-Higgs final states through loop-induced processes. Thus, I focus on the processes $μ^+μ− → γγ → h^0h^0,A^0A^0,$ and $μ^+μ− → γγ → h^0h^0h^0$ via photon fusion, utilizing the Effective Photon Approximation for cross-section predictions. Our analysis includes contributions from singly and doubly charged Higgs bosons and their couplings to CP-even scalars. I have established my own parameter scanning method, as taking the masses of the scalars as inputs is challenging due to model consistency constraints.
