Description
Double Higgs production plays a crucial role in assessing the Higgs self-coupling (trilinear Higgs coupling), which is responsible for endowing elementary particles with mass and shaping the Higgs potential. Measuring the trilinear Higgs coupling at proton colliders necessitates high luminosity due to the rarity of processes involving it in the Standard Model. Nonetheless, muon colliders offer distinct advantages over proton colliders, potentially mitigating some measurement challenges associated with the trilinear Higgs coupling. My talk would be based on my recent publication (arXiv:2312.12594v1), focusing on investigating the production of two Higgs particles through the interaction of high-energy muon beams emitting collinear photons. This analysis was conducted within the framework of the Higgs Triplet Model. The cross sections depend on the hierarchy between the doubly charged Higgs boson and the singly charged Higgs boson within the context of the Higgs triplet model. Moreover, I employed both the Effective Photon Approximation (EPA) method and EW PDF to establish parton distribution functions (PDFs) and determine the total cross sections of these processes. Throughout the analysis, I examined decoupling limits and weak coupling decoupling limits.
