Long-lived sterile neutrinos from an axionlike particle at Belle II
Zeren Simon Wang, Yu Zhang, Wei Liu
Axionlike particles (ALPs) can be produced in meson decays via tree-level quark-flavor-violating couplings, and decay to a pair of sterile neutrinos if also coupled to them. Such l…

Searching for heavy neutral leptons coupled to axion-like particles at the LHC far detectors and SHiP
Zeren Simon Wang, Yu Zhang, Wei Liu
In hidden-sector models, axion-like particles (ALPs) can couple to heavy neutral leptons (HNLs), leading to rich phenomenologies. We study ALPs produced from - and -meson dec…

Searching for long-lived light neutralinos and axionlike particles at the SHiNESS experiment
Zeren Simon Wang, Yu Zhang, Wei Liu
Recently Soleti et al. [JHEP03(2024)148] proposed a new experiment called SHiNESS at the upcoming European Spallation Source (ESS) facility, making use of the 2-GeV proton beam the…
