Abstract:
The spontaneous conversion of muonium to antimuonium is one of the interesting charged lepton flavor violation phenomena, offering a sensitive probe of potential new physics and serving as a tool to constrain the parameter space beyond the Standard Model. Utilizing a high-intensity muon beam, a Michel electron magnetic spectrometer and a positron transport solenoid together with a positron detection system, Muonium to Antimuonium Conversion Experiment (MACE) aims to discover or constrain this rare process at the unprecedented level. Meanwhile, the muon intensity frontier will also drive the detection technology across the road such as muSR and muography.
Biography:
Jian Tang is a Professor at School of Physics in Sun Yat-sen University. He did a PhD (2008-2011) from Wuerzburg University in Germany, working on neutrino phenomenology. After that, he moved to University of Alberta in Canada, developing the low-background acrylic vessel for Dark Matter experiment DEAP-3600 and continued with Germanium detector R&D in Max-Planck-Institute for Physics in Germany. In 2015, he started an associate professor position and was promoted to a full professor in SYSU in 2022, focusing on new physics searches with leptons w participating in the experiments JUNO and COMET. He proposed the muonium to antimuonium conversion experiment (MACE) and led a team to actively design the experiment for China initiative muon beamlines. He was selected as one of the outstanding young scientists at CAS Center for Excellence in Particle Physics twice in 2019 and 2020.
