    Beyond the standard model with scalars: long-lived particles and dimuon Higgs decay
    (2025) Norero Cárdenas, Sebastián; Díaz, Marco A.; Pontificia Universidad Católica de Chile. Facultad de Física
    This thesis explores two extensions of the Standard Model. The first modifies the Scotogenic Model to explain deviations in Dimuon Higgs decays, while satisfying LFV constraints. The second extends the Georgi-Machacek model by incorporating a type-II seesaw, leading to a long-lived doubly charged scalar. Both models offer collider signatures, with one probing loop-induced Higgs decays and the other emphasizing LLP searches. Future experiments will be crucial in testing these predictions.
