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.
This paper investigates the impact of adopting an -vacuum instead of the standard Bunch-Davies vacuum on inflationary observables within the Starobinsky model, concluding that Planck data and sub-millimeter gravity constraints severely limit the viability of -vacua as a de Sitter-invariant alternative.
This paper introduces and validates an unbinned method using normalizing flows to extract the CKM angle from decays, demonstrating its ability to accurately recover and other parameters from Monte Carlo data while propagating statistical uncertainties through ensemble training.
This paper introduces SCALAR, a structured Actor-Critic-Judge framework that demonstrates how multi-turn dialogue and specific critic feedback strategies, particularly in asymmetric pairings, significantly enhance AI performance on complex theoretical physics problems, while revealing that model scaling alone cannot overcome the hardest reasoning bottlenecks.
The paper introduces SIRENA, a Python and C++ implementation of the Laporta algorithm that automates the reduction of multi-loop sum-integrals in finite-temperature quantum field theory, successfully validating the framework against known results and providing new reductions for 3-loop fermionic sum-integrals alongside a novel analytic factorization formula for 2-loop cases.
This paper investigates the general structure of multi-axion solutions to the strong CP problem, deriving a universal sum rule that reveals diverse phenomenological patterns and mass-coupling relations beyond the standard single-axion paradigm, thereby motivating an expanded experimental search program.
This paper introduces a modular quantum circuit primitive that models QCD parton splitting dynamics by encoding helicity entanglement and momentum-sharing fractions, successfully validating the approach against LHC data and demonstrating its feasibility on current superconducting quantum hardware.
This paper derives the propagator for a massive charged vector boson in a constant magnetic field using the Ritus eigenfunction method in the unitary gauge, providing a detailed analysis of Landau-level polarization vectors, formulating the LSZ reduction formula for radiative corrections, and establishing a systematic connection to Schwinger proper-time representations that reveals a slight discrepancy with previous literature.
This paper formulates and numerically solves the three-quark Bethe-Salpeter equation for baryons in Minkowski-space QCD using the light-cone gauge, demonstrating that the leading-order valence truncation reproduces the Bars-Durgut equation and yields a ground-state mass and Regge trajectory consistent with previous results and experimental trends while providing a framework for calculating various structure observables.
This paper demonstrates that the Inert Two-Higgs Doublet Model (IDM) parameter space explaining Galactic Center gamma-ray and AMS-02 antiproton anomalies via annihilation in the 70–75 GeV dark matter mass range can be effectively probed and largely tested at the High-Luminosity LHC through a novel mono- channel-separation strategy targeting specific inert scalar mass splittings.
This paper demonstrates that Cho-Maison-like monopole configurations can be constructed in a broad class of gauge theories with electroweak-type symmetry breaking and establishes that the Cho-Maison monopole serves as the low-energy effective description of an 't Hooft-Polyakov monopole, specifically emerging from the Pati-Salam model after integrating out heavy degrees of freedom.
