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 proposes a unified theoretical framework for dense QCD matter in the Veneziano large- limit, identifying four distinct phases—including two types of partial deconfinement driven by string or baryon condensation—and suggesting that their interplay naturally gives rise to the QCD critical point.
This paper revises the leading-order hadronic vacuum polarization contribution to the muon anomalous magnetic moment () derived from data by calculating improved long-distance electromagnetic corrections within resonance chiral theory, resulting in a value that deviates from the latest Fermilab measurement by 2.7.
This paper investigates baryon-number-violating processes in the system using Standard Model Effective Field Theory, demonstrating that while current experimental limits on neutron-antineutron oscillations and dinucleon decays constrain the parameter space, these transitions probe complementary energy scales up to TeV that are difficult to access via indirect bounds at BESIII.
This paper proposes a five-dimensional warped anti-de Sitter inflation model with a finite initial time, demonstrating that the interaction between a UV-brane-localized inflaton and a dynamically evolving IR brane produces a two-field hyperbolic inflation scenario that generates observable deviations in the cosmic microwave background, specifically a blue tilt in the adiabatic power spectrum and oscillatory features in the tensor spectrum at large scales.
This paper derives the scalar damping rate from kinetic theory for top quarks and weak gauge bosons in a Standard Model-like theory, validating the phenomenological friction term used in hydrodynamical simulations and confirming that local damping pressure cannot exceed the pressure from runaway bubble walls.
This paper investigates decays using U-spin symmetry and finds that while the Standard Model can accommodate the data with free parameters, imposing theoretically motivated hierarchies leads to significant tensions—particularly in modes like —which cannot be fully resolved by simplistic new physics scenarios without invoking large non-factorizable contributions.
This study investigates cosmological constraints on long-lived particles decaying into dark matter via dimension-six effective operators, analyzing how such decays affect Big Bang Nucleosynthesis and the effective number of neutrino species to delineate the allowed parameter space consistent with observational data.
This paper demonstrates that the masses of highly excited meson states in the 't Hooft model can be accurately determined using a simple quantum-mechanical model with a linear potential, reproducing 't Hooft's mass spectrum in the ultrarelativistic limit while revealing exponentially suppressed finite widths for relativistic levels.
This paper presents a complete analytic calculation of background-induced forces from quadratically coupled ultralight scalar dark matter, revealing a distinctive Earth-screening frequency-band structure that enables significantly enhanced sensitivity for equivalence-principle experiments like MICROSCOPE, Galileo Galilei, and STE-QUEST.
This paper proposes a dark energy model within Unimodular Gravity where neutrino interactions mediated by a light scalar field generate dynamical dark energy with either monotonic or non-monotonic evolution, finding that such scenarios are compatible with current cosmological observations for specific neutrino mass and coupling ranges.
