Probing the dark axion portal via decays at BESIII and STCF
Zeren Simon Wang, Dazhuang He, Yu Zhang
Large numbers of mesons can be resonantly produced at BESIII and STCF at the center-of-mass energy ~GeV. Such mesons may undergo rare decays into an axi…
Long-lived sterile neutrinos from axionlike particles at the Super Tau-Charm Facility
Xiaokun Li, Zeren Simon Wang, Yu Zhang +1
We study the search prospect of long-lived heavy neutral leptons (HNLs) pair produced in decays of axionlike particles (ALPs) at the proposed Super Tau--Charm Facility (STCF), focu…
Searching for apparent baryon number violation in decays at the Super Tau-Charm Facility
Zeren Simon Wang, Xin-Ru Tang, Yu Zhang +1
Observation of baryon number violation (BNV) in laboratory experiments would constitute unambiguous evidence for physics beyond the Standard Model. We propose dedicated searches fo…
Entanglement measures and Bell-type spin-correlation observables in tau-lepton pairs at the Super Tau-Charm Facility
Beizhi Yang, Yu Zhang, Zeren Simon Wang +1
Within the framework of quantum field theory and the Standard Model (SM), we investigate the prospects of studying entanglement measures and Bell-type spin-correlation observables…
Can millicharge be probed at future Super Tau Charm Facility via mono- searches?
Yu Zhang
We propose a new channel to search for millicharged particles at the future Super Tau Charm Facility (STCF) via mono- signature. For the first time, we compute the mono-…
