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…
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 a…
Probing pair production of long-lived scalars via an off-shell Standard-Model-like Higgs boson at the LHC
Lei Wang, Xianbo Yu, Zeren Simon Wang
We study the collider phenomenology of a long-lived scalar particle that arises from Higgs mixing in a broad class of Standard-Model (SM) extensions. When the mixing angle is s…
Exploring the lifetime frontier with a beam-dump experiment at CiADS
Liangwen Chen, Mingxuan Du, Zhiyu Sun +6
We propose a beam-dump experiment (BDE) at the upcoming facility of China initiative Accelerator Driven System (CiADS), called CiADS-BDE, in order to search for long-lived particle…
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…
Probing a long-lived pseudoscalar in type-I 2HDM with displaced vertices and jets at the LHC
Lei Wang, Zeren Simon Wang, Haotian Xu
In the type-I two-Higgs-doublet model, the pseudoscalar can act as a long-lived particle (LLP) for sufficiently large values of . At the LHC, the particles are pred…
