Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.

Scalar Portal Verifiable Light Dark Matter and Correlated Gravitational Wave Signatures

This paper proposes a minimal scalar portal model with vector-like fermion dark matter that resolves the tension between large direct-detection couplings and relic density constraints through a stiff-fluid pre-BBN cosmology, thereby establishing a unique correlation between terrestrial dark matter signals and a high-frequency gravitational wave background detectable by future space-based interferometers.

Dark Matter at the Kinematic Edge: Interpreting the 248 keV LZ Nuclear-Recoil Candidate

This paper proposes that the 248 keV nuclear recoil candidate observed by the LUX-ZEPLIN (LZ) Collaboration can be explained by endothermic dark matter scattering, specifically through thermal pseudo-Dirac fermion or Higgsino models with mass splittings of approximately 297–371 keV, which naturally suppress low-energy backgrounds and satisfy relic abundance and indirect-detection constraints.

Ultralight Bosons Explain the Mass-Spin Correlations in the Merging Binary Black Hole Population

This paper presents evidence that a superradiance-informed spin distribution model, driven by ultralight scalar bosons with a mass of approximately $10^{-12} \,\rm eV$ , successfully explains the observed mass-spin correlations in merging binary black holes across the Gravitational-Wave Transient Catalogs, with statistical significance increasing from GWTC-3.0 to GWTC-5.0.

⚛️ phenomenology

Entanglement entropy minimization and global symmetry violation in scatterings

This paper conjectures and provides evidence that the minimization of entanglement entropy in scattering processes acts as a selection principle that suppresses interactions violating global symmetries, thereby offering a potential information-theoretic explanation for the rarity of certain Beyond-the-Standard-Model phenomena.

Next-to-Leading-Order Multi-Jet Merging of Higgs Boson Production via Vector Boson Fusion in the Presence of Anomalous Couplings

This paper presents a detailed simulation study of Higgs boson production via vector boson fusion with anomalous couplings at the LHC, utilizing a next-to-leading-order multi-jet merging scheme in Herwig and VBFNLO to demonstrate the robustness of azimuthal angle observables against QCD radiative corrections.

Strong Constraints on Higgsino Dark Matter from Solar Capture

By analyzing the expected high-energy neutrino flux from Higgsino dark matter annihilation in the Sun and comparing it with IceCube's null results, the study establishes a robust lower limit on the mass splitting ( $\delta > 566$ keV) that rules out the interpretation of a recent LZ event as endothermic inelastic scattering of Higgsino dark matter.

The $H^H^V$ charge couplings from light-cone sum rules

This paper presents a rigorous determination of strong charge couplings $g_{H^*H^*V}$ using light-cone sum rules with next-to-leading-order corrections and next-to-next-to-leading power contributions, yielding a robust universal static coupling $\beta = 0.73 \pm 0.13$ while demonstrating the couplings' insensitivity to heavy-quark mass breaking and the current dominance of non-perturbative uncertainties over SU(3) flavor symmetry breaking effects.

Zero-damped modes of near-extremal Reissner--Nordström black holes from exact WKB

This paper demonstrates that exact WKB methods provide a powerful and systematically improvable framework for analytically computing the zero-damped mode spectrum of near-extremal Reissner--Nordström black holes with higher accuracy than previous studies.

Inelastic Dark Photon Dark Matter for the LUX-ZEPLIN High-Recoil Event and the Galactic Halo Gamma-Ray Excess

This paper proposes that a 420 GeV dark photon dark matter model, featuring an inelastic transition to a nearly degenerate vector partner mediated by a light scalar, can simultaneously explain the LUX-ZEPLIN 248 keV nuclear-recoil event and the Galactic halo gamma-ray excess without altering the original model's relic abundance or halo phenomenology.

Radiative and Dalitz decays of $\Upsilon(1S)$ in the light of the ATOMKI X17 anomaly

Using the Covariant Confined Quark Model, this paper calculates Standard Model predictions for the radiative and Dalitz decays of $\Upsilon(1S)$ and investigates the potential contribution of the hypothetical ATOMKI X17 vector boson to the Dalitz channel.
