Description:

The Large Hadron Collider(LHC) at CERN offers a tremendous amount of data to explore the unsolved mysteries in elementary particle physics.

Long-lived Particles(LLP) are predicted by a wide range of theories beyond the Standard Model, yet able to escape the majority of current searches at the LHC. In this talk, I will discuss a novel signature, called Muon Detector Shower(MDS), which was recently invented to target generic LLP searches at the CMS experiment. Since MDS is using the outermost subsystem in CMS, it is naturally sensitive to LLPs with longer life-time. The calorimetric nature of MDS also makes it an ideal tool for a wide range of model independent searches. These unique features of MDS allows us to explore un-probed territories with LHC data. I will discuss the searches performed with MDS signature so far, highlight the improvement implemented in LHC Run 3, and outline the potential capability of MDS in the HL-LHC era.
