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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper introduces a modification of QCD sum rules using Euclidean time correlators in coordinate space instead of Borel transforms, demonstrating that while nucleon mass and residue can be roughly estimated, this approach suffers from significantly larger uncertainties and a lack of a stable working window compared to traditional Borel sum rules.
This paper presents the leading-color two-loop QCD corrections for Higgs-plus-two-jet production in the heavy-top limit, providing analytic expressions for finite helicity amplitudes derived via numerical unitarity and a novel partial fraction decomposition algorithm, alongside a stable numerical implementation and an analysis of their singularity structure.
This paper demonstrates that quantum fluctuations from squeezed coherent states in nonlinear Compton scattering effectively manifest as frequency modulation of the background field, significantly altering the emission spectrum and total photon yield even at currently available squeezing levels.
This paper predicts the existence of a lighter scalar partner, , for the recently observed tetraquark based on CMS data, urging further experimental investigation to confirm an S-wave multiplet of states and distinguish between competing theoretical models.
This paper employs Landau singularity analysis within the Schwinger-Keldysh effective field theory framework to systematically identify frequency-space singularities induced by nonlinear interactions, thereby determining the power-law late-time relaxation modes of gapless fluctuations without explicitly performing loop integrations.
This paper presents a systematic, Lorentz covariant spinor-helicity formalism that extends the traditional multipole expansion to construct complete and linearly independent orbital-spin bases for form factors of arbitrary spin particles, demonstrating their equivalence to established expansions while providing a universal construction formula for arbitrary tensor operators.
This paper presents a precise determination of the strong coupling constant through a global fit of heavy jet mass data, utilizing state-of-the-art theoretical predictions that combine fixed-order calculations, multiple resummation orders, and first-principles power corrections to demonstrate the critical role of resummation in achieving robust results and revealing evidence for negative power corrections in the trijet region.
This paper presents the quantization of massive Majorana neutrinos in background matter using Weyl spinors and propagator construction, alongside a Hamiltonian formalism analysis of both these neutrinos and classical Dirac particles in vacuum.
This paper reviews two inflationary models—volume modulus (inflection point) inflation and fibre inflation—realized within the perturbative Large Volume Scenario framework of type IIB superstring compactifications, while also discussing their concrete global embeddings using explicit Calabi-Yau orientifolds.
The paper proposes a mechanism called "sphalerogenesis" to explain the baryon asymmetry of the universe through the CP-violating decay of electroweak sphalerons mediated by a dimension-six operator, suggesting a new physics scale of approximately 38 TeV that could be tested via future electron electric dipole moment measurements.
