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.
The paper introduces SAILIR, a self-supervised machine learning framework that utilizes a transformer-based classifier to perform Feynman loop integral reduction with bounded memory consumption, offering a scalable alternative to traditional Laporta-based methods that struggle with memory limitations as complexity increases.
This paper develops a worldline technique based on the method of images to study the effective action of Yang-Mills theories on manifolds with boundaries under relative or absolute boundary conditions, verifying the approach through Seeley-DeWitt coefficient calculations and applying it to determine gluon production rates in chromoelectric fields near a boundary.
This paper investigates quasinormal modes and greybody factors within a parametrized framework for modified gravity, analyzing their dependence on correction orders and polynomial powers while testing the validity limits of the proposed correspondence between these two phenomena.
This paper demonstrates that the weak-field limits of the Schwarzschild, Kerr, Reissner-Nordström, and Kerr-Newman black hole metrics can be reconstructed from quantum scattering amplitudes using the KMOC formalism, specifically revealing unique interference terms in the Kerr-Newman case that arise from combined gravitational and electromagnetic interactions.
This paper establishes a historical optical foundation for stationary vacuum Kerr--Schild spacetimes by demonstrating how a single complex optical seed, derived from expansion and twist, algebraically reconstructs the spacetime congruence and serves as the normalized zeroth-copy data that generates both the metric profile and the associated single-copy gauge field within the double-copy framework.
This paper establishes a direct link between near-maximal Bell-CHSH violations in the vacuum state of free -dimensional spinor fields and the spectral theory of Carleman and Hankel operators, demonstrating that the Tsirelson bound is approached through the spectral edge in the massless case and exponentially damped variants in the massive case.
This paper reformulates the double-logarithmic four-graviton Regge sector in -extended supergravity as a rank-two twisted period system, providing a uniform description that connects various integral representations, simplifies the dependence on the number of supersymmetries through differential equations and recursion, and offers a Hermite-polynomial construction for low-even theories.
By modeling string dynamics within finite-lifetime causal diamonds rather than assuming eternal existence, the paper demonstrates that tensionless strings emerge exclusively at their moment of birth, revealing a new phase characterized by a global, ultra-local Carrollian structure.
This paper demonstrates that while the Kerr-Schild double copy introduces an enlarged, infinite-dimensional residual symmetry structure in both Yang-Mills and gravity, a fundamental mismatch exists where the gravitational sector's apparent conformal symmetries are shown to be BRST-trivial, leaving only global isometries as physical symmetries, unlike the non-trivial infinite-dimensional algebra found in the gauge theory side.
This paper proposes that topological quantum critical points separating non-invertible chiral topological orders in (2+1) dimensions are described by a non-compact conformal manifold where the critical theory's topological angle is uniquely determined by the harmonic mean of the adjacent gapped phases' braiding angles, maintaining exact scale invariance without supersymmetry.
