An Axial-Vector Leptophilic Fifth Force Sourced by Solar Neutrinos

Rundong Fang, Ji-Heng Guo, Jia Liu +2

We investigate long-range, purely leptophilic axial-vector interactions mediated by a light gauge boson that couples to charged leptons and, by weak symmetry, to left-handed n…

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 $…

Scattering Entanglement Entropy and Its Implications for Electroweak Phase Transitions

Jia Liu, Masanori Tanaka, Xiao-Ping Wang +2

We investigate the connection between the entanglement entropy in scattering processes and the dynamics of electroweak phase transitions. Recent work has shown that the scattering…

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…

Implications of the KM3NeT Ultrahigh-energy Event on Neutrino Self-interactions

Yuxuan He, Jia Liu, Xiao-Ping Wang +1

Neutrino self-interactions (SI) mediated by light bosonic particles can produce characteristic spectral dips in astrophysical neutrino fluxes, thereby altering the expected ener…

Testing the Fifth Force on Lepton Spins through Neutrino Oscillations

Rundong Fang, Ji-Heng Guo, Jia Liu +1

We investigate a fifth force mediated by a light vector boson that couples to lepton spins, characterized by axial-vector couplings to leptons and vector couplings to nucleons. Thi…
