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 electromagnetic corrections to -meson decay constants and light-cone distribution amplitudes within heavy-quark effective theory, demonstrating how QED effects extend the amplitudes' support to negative momenta and deriving model-independent expressions for their asymptotic behavior in terms of pure QCD multi-particle distributions.
This paper demonstrates that dark-sector interactions, specifically an attractive finite-range scalar force balancing degeneracy pressure, can allow eV-scale fermionic dark matter to form dwarf-galaxy-sized structures, thereby evading the conventional Tremaine-Gunn mass bounds that typically require much heavier fermions.
This paper proposes using cross-rapidity net-baryon cumulants to distinguish QCD critical fluctuations from global baryon-number conservation effects by exploiting their opposite correlation signs, thereby offering a refined strategy for identifying the critical endpoint in beam-energy-scan experiments.
This paper proposes that the 248-keV event observed by LZ can be explained by near-threshold upscattering of 1.08-TeV thermal Higgsino dark matter within a high-scale supersymmetric framework featuring a Peccei-Quinn symmetry, which simultaneously addresses the strong-CP problem, suppresses proton decay, and resolves various cosmological issues.
This paper investigates the cosmological viability of hairy black holes formed via spontaneous symmetry breaking in Einstein-Scalar-Gauss-Bonnet theory and concludes that, to avoid tachyonic instabilities during the post-inflationary phase, only ultralight primordial black holes with masses of a few grams can successfully develop scalar hair.
This paper resolves the challenge of applying the nonpole formalism to the Sivers effect in $pp$ collisions by developing a generalized method that successfully reproduces known results despite the complexities of initial- and final-state interactions.
This paper proposes using fiducial hadronic recoil combined with a tagged jet to suppress Sudakov broadening and competing azimuthal harmonics from final-state soft radiation, thereby enabling precision gluon transverse-momentum-dependent (TMD) tomography by significantly enhancing the signal of the distribution while minimizing soft-radiation effects without requiring a veto.
This paper presents a method to compute scheme-independent leading infrared divergences and construct finite linear combinations of integrals by analyzing and canceling permanent pinches through residue integration along desingularized pinch varieties, applicable to massless, mixed, non-planar, and higher-power propagator integrals.
This paper demonstrates that by subtracting hadronic recoil measured within a specific rapidity interval from the boson's transverse momentum, detector geometry can effectively suppress QCD radiation to unmask gluon saturation signatures in forward production, thereby lowering the effective hard scale and enabling a clearer probe of nonlinear small- QCD in proton-nucleus collisions.
This paper investigates how a flavor-dependent extension of the Standard Model can simultaneously address the muon anomalous magnetic moment and predict lepton-flavor violation processes with branching ratios potentially within the reach of future experiments.
