Abstract

We propose here a possible experiment by Probing and Knocking with Muons, to measure muon properties, and directly detect light mass dark matter and charged lepton flavour violation physics, through muons scattering with abundant atmospheric muons or accelerator beams. As a first step, we plan to use the free cosmic-ray muons interacting with dark matter in a volume surrounded by tracking detectors, to trace possible interaction between dark matter and muons. Secondly, we will interface our device with domestic or international muon beams. Due to much larger muon intensity and focused beam, we anticipate the detector can be made further compact and the resulting sensitivity on dark matter searches will be improved. Our methods can have advantages over `exotic' dark matter which are either muon-philic or slowed down due to some mechanism, and sensitivity on dark matter and muon scattering cross section can reach as low as microbarn level.

Biography

Dr. Qiang Li is a Boya professor, and the deputy head of the Technical Physic Department, at the School of Physics, Peking University. He received support from the National Fund for Outstanding Youth in 2023. He has long been committed to multi-boson physics research at the LHC CMS experiment. His recent achievements include: the first observation and discovery of several vector boson scattering and polarisation scattering processes; development and applications of multi-boson taggers, such as searching for new particles beyond the Standard Model through two-boson and three-boson processes. Qiang has also been committed to the software and physics research of future colliders, and proposed new types of collisions, such as possible electron-muon and neutrino-lepton colliders, for which he received support from the NSFC Original Exploration fund in 2021. He took level-2 convenerships under the CMS Physics Generator and Computational Software release planning groups. Since 2023, he has served as an advisory member of the CMS Collaboration Committee and a member of the CMS School Committee.
