Collider Spin Tomography with Missing Neutrinos
Tengyu Ai, Qi Bi, Yuxin He +3
The paper presents a method to extract spin information from collider events with invisible neutrinos by treating the visible measurements as a coarse‑grained quantum measurement,…
Ultimate Quantum Precision Limit at Colliders: Conditions and Case Studies
Tengyu Ai, Qi Bi, Yuxin He +2
We investigate whether collider experiments can reach the quantum limit of precision, defined by the quantum Fisher information (QFI), using only classical observables such as part…
Probing Scalar-Mediated Sterile Neutrinos with Gravitational Wave and Colliders Signals
Qi Bi, Jinhui Guo, Jian Liao +2
We propose a UV-complete extension of the Standard Model in which a gauge-singlet scalar acquires a vacuum expectation value, generates a Majorana mass for a sterile neutrino $…
Long-lived Sterile Neutrino Searches at Future Muon Colliders
Qi Bi, Jinhui Guo, Jia Liu +2
We explore the potential of studying sterile neutrinos at a future high-energy muon collider, where these particles can generate small active neutrino masses via the seesaw mechani…
