An Axial : UV Completion and Experimental Searches

Rundong Fang, Jinhui Guo, Ming Li +3

We propose an anomaly-free and renormalizable axial model and study its experimental signatures for masses from the MeV scale to the TeV scale. The opposite…

Flavor--Kinetic Entanglement Production from Decay and Scattering at Finite Density

Zekun Li, Jia Liu, Xiao-Ping Wang +1

We extend the scattering-entanglement dictionary to finite-density environments by investigating the flavor--kinetic bipartition of the Hilbert space. We show that tracing over kin…

Collider Spin Tomography with Missing Neutrinos

Tengyu Ai, Qi Bi, Yuxin He +3

Missing neutrinos need not destroy collider spin tomography. We formulate the visible measurement under kinematic ambiguities arising from invisible particles as a coarse-grained p…

Supermassive Primordial Black Holes from a Catalyzed Dark Phase Transition for Little Red Dots

Jinhui Guo, Jia Liu, Masanori Tanaka +2

JWST has revealed an abundant population of compact, low-metallicity "Little Red Dots" (LRDs) at high redshift, challenging conventional scenarios in which supermassive black holes…

Ultralight Scalar Dark Matter with Off-Diagonal Flavor Couplings

Jinhui Guo, Jia Liu, Chenhao Peng +2

Ultralight dark matter can behave as a coherent background field and induce time-dependent modifications of Standard Model parameters. We study a scenario in which a real ultraligh…

Parameter Inference from Final-State Entanglement in Higgs Decays

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

The decay out-states of unstable Standard Model (SM) particles provide a unique, well-defined intrinsic quantum-information probe of the SM parameter space. We use Higgs decays as…

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 $…

Probing Purely Inelastic Scalar Dark Matter Across Colliders and Gravitational Wave Observatories

Jinhui Guo, Jia Liu, Chenhao Peng +1

We propose and study a purely inelastic scalar dark matter model, where two real scalars-dark matter and its excited partner interact with the Standard Model via a Higg…

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…

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…

Lepton flavor of four-fermion operator and fermion portal dark matter

Yuxuan He, Gang Li, Jia Liu +2

We study the ultraviolet realization of semileptonic four-fermion operator that incorporates Majorana dark matter (DM) in both lepton-flavor-conserving (LFC) and…

Muon g-2, Long-Range Muon Spin Force, and Neutrino Oscillations

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

Recent studies have proposed using a geocentric muon spin force to account for the anomaly, with the long-range force mediator being a light axion-like particle. The medi…

Enhanced Monochromatic Photon Emission from Millicharged Co-Interacting Dark Matter

Mingxuan Du, Jia Liu, Xiao-Ping Wang +1

We study a millicharged co-interacting dark matter scenario, where the primary dark matter constituent is the dark photon and the secondary component is the fermion . In th…
