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.

The author proposes and validate a novel perturbation theory that eliminates Coulomb-phase infrared divergences in semiclassical scattering by utilizing Coulomb wavefunctions and propagators to correctly match asymptotic states, successfully reproducing exact results at leading and next-to-leading orders while revealing an underlying Runge-Lenz symmetry.
This paper proposes that the linearization of gradient-based learning in deep neural networks, particularly in the infinite-width limit, stems from weak correlations between the first and higher-order derivatives of the hypothesis function, a principle used to derive bounds on training deviations and characterized via a novel method for analyzing random tensors.
This paper demonstrates that by canonically quantizing a charged scalar in a Coulomb background and fully solving the asymptotic Hamiltonian, one can systematically restore unitarity, causality, and crossing symmetry while establishing an analytic link between Coulomb phase and real radiative divergences, offering an alternative to the Faddeev-Kulish approach for resolving infrared issues in long-range force theories.
This paper extends the connection between torus knots and Virasoro minimal models by utilizing 3D–3D and bulk–boundary correspondences to demonstrate that 3D gauge theories associated with torus-knot complements flow to specific boundary chiral algebras, thereby providing a systematic algorithm to derive rational VOA characters directly from the combinatorial data of non-hyperbolic knot triangulations.
This paper constructs a novel family of non-supersymmetric, asymptotically locally AdS black string solutions in five-dimensional gauged supergravity and demonstrates that their supersymmetric, non-extremal limit provides a holographic dual to the topologically twisted index of 4d SCFTs on , with the supergravity on-shell action matching the field theory result in the large limit.
This paper demonstrates that the bar-cobar construction for homotopy algebras reformulates the equations of motion for arbitrary gauge theories into universal quadratic Maurer-Cartan equations involving extended multilocal fields, where every solution is gauge-equivalent to a physical solution of the original theory.
This paper clarifies that while gauged WZW models and GKO coset constructions are closely related, they differ by a topological field theory factor, with the former's partition function exceeding the latter's by the dimension of a specific commutative Frobenius algebra derived from the underlying modular tensor category.
This paper investigates the rich collision dynamics of boosted sphalerons in a (1+1)-dimensional deformed scalar field theory with false vacua, revealing diverse outcomes such as kink-antikink pair production, oscillon formation, and the emergence of long-lived false-vacuum bubbles that collapse and re-expand before decaying.
This paper introduces new magnetic quivers for 5d Spin(N) gauge theories with spinor hypermultiplets, revealing novel 3d theories whose Coulomb branches are isolated symplectic singularities and demonstrating how wreathings and foldings realize quivers for non-simply laced nilpotent orbit closures.
This paper demonstrates that flat-space on-shell amplitudes can exactly determine the channel-basis mixing projectors for electromagnetic and gravitational perturbations of a Reissner-Nordström black hole, while also revealing that these alignments are spoiled by finite-mass recoil effects and require spin-induced angular-mode mixing in rotating generalizations.
