SUMMARY:Speaker: Kehang Bai (University of Oregon) - Title: Exploring the Dark Sector with Low-Mass\, Long-Lived Dark Photons and the ATLAS Silicon Tracker
DESCRIPTION:Research Progress Meeting \nDate: December 9\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Kehang Bai  (University of Oregon) \nTitle: Exploring the Dark Sector with Low-Mass\, Long-Lived Dark Photons and the ATLAS Silicon Tracker \nAbstract: The rich phenomenology of dark sector models offers exciting opportunities for discovering new physics at the Large Hadron Collider. In this talk\, I will present the first ATLAS search for low-mass\, long-lived dark photons with displaced vertices in the silicon tracker. This novel signature expands sensitivity to regions of parameter space beyond conventional resonance searches. I will highlight the experimental challenges of searching for long-lived particles in the low-mass regime and emphasize the importance of detailed detector understanding. Finally\, I will discuss key aspects of the ATLAS Inner Tracker upgrade for the upcoming high-luminosity era of the Large Hadron Collider. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037
