【 摘 要 】

Searches for exotic Higgs boson decays are well motivated by various theoretical models, as well as the constraints from Higgs boson measurement results. The focus is on exotic Higgs boson decays to a pair of beyond-the-Standard-Model spin-0 particles $a$. This dissertation conducts two analyses for exotic Higgs bosons decaying into leptons, which are $H\rightarrow2a\rightarrow4\mu$ and $H\rightarrow2a\rightarrow4\tau$, and target the mass ranges of $1
