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
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,…
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…
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 ene…
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…
