Unlocking the CMS Experiment to Catch Long-lived Particles
Cristian Peña, Fermilab,

Limited attendance in 269 Lauritsen.

Enabling new long-lived particles (LLPs) searches at the LHC presents HEP research with unique opportunities. Introducing novel experimental techniques to identify and reconstruct LLPs will open up new possibilities for discoveries with striking signatures. I will present new long-lived particles searches, with a focus on the CMS Muon System result, which significantly pushed the envelope of LLP exploration. I will follow a detector-based path and discuss the current efforts and significant extensions. I will also discuss new ideas for increasing the acceptance and developing efficient triggers. As we enter the high luminosity era of the LHC, the CMS detector will be equipped with precision timing information in the form of two dedicated systems: the barrel timing layer and the endcap timing layer. These revolutionary upgrades will enable CMS with 4D-reconstruction for the first time, and thus significantly enhance the physics reach of the LHC.
