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…
Updated sensitivities to heavy neutral leptons at the LHC far detectors and SHiP
Zeren Simon Wang, Yu Zhang
In recent years, a number of experiments dedicated to searches for long-lived particles (LLPs) have been proposed, approved, or have entered operation. While the sensitivities of t…
Probing dark-state electromagnetic form factors at future linear electron-positron colliders with polarized beams
Zhong Zhang, Yu Zhang, Zeren Simon Wang +1
We study the electromagnetic form factors of electrically neutral dark-sector particles in this paper. Concretely speaking, we focus on operators that can lead to interactions of f…
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…
