Description

In this talk, I will present a reinterpretation of selected LHC searches for Higgs boson decays into long-lived particles (LLPs) in the context of a Standard Model plus scalar (SM+s) Dark Higgs model. The analysis is based on public data available in HEPData and focuses on comparing the sensitivity of different search strategies and final states. The aim is to explore how various approaches can probe different regions of the model parameter space and to examine the extent to which they provide complementary information.
