Abstract

Long-lived particles (LLPs) provide an intriguing glimpse into physics beyond the Standard Model. Their detection, however, presents significant challenges due to their extended lifetimes. This paper explores a hypothetical scenario by investigating the sensitivity of a Belle II-like detector in a proton-proton environment, similar to the Large Hadron Collider (LHC) experiment setup. We investigate the detector's sensitivity to a specific LLP model: proton-proton collisions producing slepton pairs that decay into electrons and binos χ̃10. Using the Displaced Decay Counter (DDC) framework, we implemented a detector with Belle II's geometry and performance characteristics into the DDC framework to evaluate its performance. Our analysis demonstrates the superior sensitivity of this Belle II-like detector compared to far detectors of LHC for this LLP model, highlighting its potential for probing new physics.
