Description
Long-lived particles appear in many new physics models.
Especially, the particle with decay length below 1 m can generate various displaced signatures at the colliders and such events are expected to have low background. There are huge opportunities in this lifetime parameter. In this context, we study not only the experimental reach of the LLP searches at colliders (LHC, HL-LHC, Belle II) but also how to reconstruct the event with displaced vertex and missing energy which can provide the understanding for the underlying new physics. We also give challenges and future prospects of the LLP searches.
