hep-ph papers | Gist.Science

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.

Medium separation scheme effects on the magnetized and cold two-flavor superconducting quark matter

This study demonstrates that applying the Medium Separation Scheme (MSS) alongside Magnetic Field Independent Regularization (MFIR) to the Nambu--Jona-Lasinio model of magnetized two-flavor color superconducting quark matter eliminates unphysical oscillations and ensures positive magnetization, thereby correcting artifacts found in traditional approaches that fail to properly separate medium effects from vacuum contributions.

Gravitational-Wave Signals for Supernova Explosions of Three-Dimensional Progenitors

This study analyzes gravitational-wave signals from two 3D core-collapse supernova simulations of massive progenitors with vigorous pre-collapse shell activity, finding that while the resulting signals are detectable by current and future interferometers, they lack unique features directly attributable to the pre-collapse dynamics despite exhibiting distinct characteristics compared to previous models.

Determining $G$ with Laser Spectroscopy to 38 ppb

This paper proposes a precision measurement using a 3 mW tunable diode laser and a 1 T permanent-magnet assembly in a Mach-Zehnder interferometer to detect axion-photon conversion, aiming to determine the gravitational constant $G$ with a 38 ppb accuracy—a 600-fold improvement over current standards—by measuring the axion Compton frequency.

Rotation of the polarization plane in axion fields: application to neutron star polar cap regions

This paper investigates the rotation of the polarization plane of electromagnetic waves caused by strong, spatially varying axion fields in neutron star polar caps, deriving both perturbative and non-perturbative solutions to demonstrate that such rotation requires axion inhomogeneity and predicting that the resulting nanosecond-scale gap-filling times could be detectable with atomic clocks.

Entanglement Signatures of CPT Violation in Neutrino Oscillations

This paper demonstrates that entanglement entropy serves as a sensitive probe for CPT-violating Planck-scale physics in neutrino oscillations by revealing a distinct asymmetry between neutrino and anti-neutrino entropy profiles that is controlled by Majorana phases.

A Determination of the Top Mass from a Global PDF Analysis

This paper presents an indirect determination of the top-quark pole mass as $172.80 \pm 0.26$ GeV by performing a global analysis of parton distribution functions within the NNPDF framework, which incorporates high-precision QCD and electroweak corrections, toponium contributions, and lattice constraints on $\alpha_s$ while refitting PDFs to properly correlate uncertainties across various ATLAS and CMS measurements.

Higgs Boson Spookiness: Probing Quantum Nonlocality with Spacetime-Resolved $H\rightarrow\tau^+\tau^-$ Decays

This paper proposes that a future precision $ee$ Higgs factory could perform the first spacetime-resolved test of quantum nonlocality in Higgs boson decays by measuring spin correlations between spacelike-separated $\tau$ lepton decays, thereby enabling the exclusion of superluminal entanglement signaling theories.

Quark-Mass Dependence of Light-Nuclei Masses from Lattice QCD and Trace-Anomaly Contributions to Nuclear Bindings

This paper presents lattice QCD calculations of light-nuclei masses across various quark masses to establish first-principles constraints on nuclear interactions and reveals that, while quark-mass contributions to binding energy are small and additive, the dominant contribution arises from the gluonic component via the QCD trace anomaly.

Misalignment from kicks: the impact of particle interactions on ultra-light dark matter

This paper demonstrates that interactions between ultra-light dark matter scalars and Standard Model or dark sector particles can significantly alter the misalignment mechanism, thereby modifying the expected amplitude of scalar oscillations and the resulting late-time dark matter abundance.

Dark photon and U(1) $_{B-L}$ gauge boson from dark Higgs boson decays at FASER and SHiP

This paper investigates the sensitivity of the FASER and SHiP experiments to dark photons and U(1) $_{B-L}$ gauge bosons produced via dark Higgs boson decays, incorporating new single-boson production channels, deriving constraints from current FASER data, and projecting future discovery potential for these models including those with freeze-in sterile neutrino dark matter.
