报告摘要

In this seminar, I will present my recent research on rare and hidden processes at the LHC, focusing on top quark flavor-changing neutral currents (FCNC) and axion-like particle (ALP) signatures. I will discuss analyses based on LHC Run 2 data, including the first evidence for single top production in association with a photon, as well as projections for probing FCNC operators using the effective field theory (EFT) framework at future colliders such as the FCC-ee or CEPC. These precision studies provide a powerful window into physics beyond the Standard Model.

Complementing these physics goals, I will also describe my technical contributions to the CMS detector upgrade, including the development and quality control of electronic circuits for the Outer Tracker, and the design and fabrication of high-speed link and control boards for the RPC muon system. These efforts are essential for enhancing detector performance at the High-Luminosity LHC and for enabling searches for long-lived particles and rare signatures. I will conclude with a perspective on how the synergy between instrumentation and physics analysis drives discovery at present and future collider experiments.
