Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper demonstrates that employing a nonlocal UV completion allows for the derivation of a fully convergent, closed-form Schwinger-parameter representation of the four-loop Higgs-gluon form factor, enabling direct numerical evaluation without standard UV subtractions while maintaining consistency with the coupling scheme in the local limit.
This paper demonstrates that for specific quadratic torsion subsectors on maximally symmetric and flat backgrounds, the one-loop effective actions and local divergences of Poincaré gauge theories with propagating torsion remain identical between their diffeomorphism-invariant and unimodular formulations, indicating that the unimodular constraint does not alter local one-loop torsion dynamics in these cases.
This paper proposes using localized lepton wave packets carrying orbital angular momentum as a tunable transverse probe in hard diffractive dijet deep inelastic scattering to characterize elliptic small- gluon geometry, revealing that specific OAM channels induce finite-yield response nodes arising from spatial cancellations rather than a loss of scattering strength.
This paper investigates the cosmological evolution of a spherical brane in a five-dimensional charged AdS bulk, demonstrating that the bulk charge induces nonsingular bouncing and cyclic or eternal expansion scenarios that resolve Cauchy horizon instabilities and remain stable under scalar perturbations and the presence of bulk strings.
This paper provides a pedagogical introduction to finite- holography by applying invariant theory to solve trace relations, thereby constructing a non-redundant set of gauge-invariant operators where primary invariants correspond to perturbative gravitational degrees of freedom and secondary invariants encode non-perturbative effects.
This paper proposes that a second law of quantum complexity, which dictates that complexity grows toward an exponential saturation value in equilibrium but can decrease out of equilibrium, is derivable from a quasistatic information quantization rule linked to the principle of least action and minimum entropy production.
This paper presents the first complete all-multiplicity proof that locality and unitarity in tree-level Tr() scattering amplitudes emerge from a single on-shell principle of hidden zeros, which are shown to enforce pole compatibility by characterizing polygon triangulations as the specific chord configurations that evade a graphical "star test."
This paper presents a quasielastic lepton-nucleus scattering model within the local density approximation that utilizes ab initio spectral functions from infinite nuclear matter, interpolated by neural networks and incorporating final-state interactions, demonstrating good agreement with experimental data for various nuclei while assessing theoretical uncertainties.
This paper demonstrates that the renormalization of a three-dimensional quartic model on a manifold with a boundary requires extending the classical action to include singular boundary coefficients and renormalizing a boundary operator to ensure consistency under manifold gluing.
This paper demonstrates that neither gamma-ray active galactic nuclei nor nearby starburst galaxies alone can explain the ultra-high-energy cosmic ray dipole observed by the Pierre Auger Observatory, necessitating a hybrid model where starburst galaxies dominate the anisotropic signal while active galactic nuclei provide a subdominant contribution.
