Seminar: Dark Shower Searches at the LHC

ABSTRACT

Dark QCD is increasing gaining attention in recent years. It predicts striking signatures at hadron colliders due to a new confining force SU(N), such as emerging jets and semi-visible jets. ATLAS has completed the first round of searches for Dark QCD. In this seminar, I will summarise those recent results and discuss some of the standalone phenomenology studies done in our group.

BIOGRAPHY

Prof. Bingxuan Liu received his undergraduate degree from the University of Electronic Science and Technology of China and his Ph.D. from The Ohio State University, where he conducted research on the search for long-lived particles in the CMS experiment. During his postdoctoral career, He joined the ATLAS experiment, working at Argonne National Laboratory and Simon Fraser University, primarily focusing on flavor tagging, track reconstruction, and the search for new physics. He served as the convener of the FTAG working group, the FTAG calibration subgroup, and the Jet Met + X physics analysis subgroup within the ATLAS collaboration. He received the 2022 ATLAS Collaboration Outstanding Achievement Award for his work on large impact parameter track reconstruction. Prof. Liu's current research focuses on the phenomenological and experimental study of long-lived particles, dark showers, and dark matter. He has published seventeen papers (including collaboration papers) in top journals such as PRL, Nature Communications, and ROPP. Prof. Liu joined the School of Science at Sun Yat-sen University as an associate professor in early 2024 and currently teaches undergraduate/graduate courses such as Machine Learning and Introduction to Particle Physics.
