Vertexing displaced diphoton decays with recoil photons at Belle II

Zeren Simon Wang, Yu Zhang

We propose a recoil-assisted strategy for vertexing displaced diphoton decays in , , using only one converted daughter photon. The initial state and recoil-pho…

Same-sign dimuon probe of charged lepton flavor violation at electron-photon colliders

Zhong Zhang, Yu Zhang, Zeren Simon Wang

Observation of charged lepton flavor violation would constitute unambiguous evidence for physics beyond the Standard Model (SM). We identify a previously unexplored same-sign dimuo…

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…

Searching for long-lived particles from stopped pions and muons at the CiADS-BDE

Zeren Simon Wang, Yu Zhang, Liangwen Chen

The CiADS-BDE is a beam-dump experiment recently proposed for searching for light, long-lived particles (LLPs) at China initiative Accelerator Driven System. Primarily thanks to th…

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 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…

Direct Production of Light Scalar in the Type-I Two-Higgs-Doublet Model at the Lifetime Frontier of LHC

Wei Liu, Lei Wang, Yu Zhang

A light pseudoscalar in the sufficient large region of type-I two-Higgs-doublet model (2HDM) can be naturally a long-lived particle (LLP). We focus on , …
