hep-th papers | Gist.Science

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.

On Gauge-Invariant Entire-Function Regulators and UV Finiteness in NonLocal Quantum Field Theory

This article demonstrates that the implementation of gauge-invariant regulators as entire functions of the covariant Laplace–Beltrami operator within the framework of the background field method induces an exponential ultraviolet damping in loop integrals without introducing new singularities, thereby providing a rigorous gauge-covariant justification for ultraviolet finiteness in nonlocal quantum field theories.

(Iso)spin from Isospin in Top-Down Holography

This paper explores how the "spin from isospin" mechanism—where gauge symmetry and spatial isometry combine into a single diagonal symmetry—manifests in top-down holographic backgrounds involving non-Abelian hedgehog monopoles, leading to angular momentum mixing in field fluctuations.

Hamiltonian formulation of the $1+1$ -dimensional $ϕ^4$ theory in a momentum-space Daubechies wavelet basis

This paper applies a momentum-space Daubechies wavelet basis within the Hamiltonian framework to investigate nonperturbative dynamics in $1+1$ -dimensional $\phi^4$ theory, successfully reproducing the strong-coupling phase transition and demonstrating systematic convergence of the critical coupling as momentum resolution increases.

Non-Abelian and Type-A Conformal Anomalies from Euler Descent

This paper classifies the non-Abelian conformal anomaly of the Euclidean conformal group in $2n$ dimensions by using the Stora-Zumino descent method applied to the Euler invariant, thereby establishing a formal connection between conformal anomalies, type-A Weyl anomalies, and 't Hooft anomaly matching.

Graph models for covariant holographic entropy I

This article constructs a graph model for covariant holographic entropies in time-dependent spacetimes by identifying a geometric condition that incorporates exposed regions and prevents unphysical shortcuts, thereby proving the equivalence between covariant and static holographic entropy cones and paving the way toward a complete covariant construction.

A QFT information protocol for charged black holes

This paper generalizes the Verlinde-van der Heijden quantum information retrieval protocol to type III von Neumann algebras relevant to Quantum Field Theory, deriving a formula for charged black hole evaporation that links the statistical dimension of superselection sectors to thermodynamics and suggests constraints on charge quantization.

Dynamical generation of fermion mass in a scalar-fermion theory with $λϕ^4$ interaction

Using the Cornwall-Jackiw-Tomboulis method, this paper demonstrates that in a scalar-fermion theory with $\lambda\phi^4$ interaction, the fermion acquires a dynamical mass through spontaneous symmetry breaking when the coupling constant exceeds a specific threshold, whereas it remains massless within a particular range of coupling values where the vacuum preserves inversion symmetry.

The asymptotic charges of Curtright dual graviton and Curtright extensions of BMS algebra

This paper constructs the asymptotic gauge charges for the Curtright mixed-symmetry field interpreted as a dual graviton in five-dimensional Minkowski spacetime, revealing a charge algebra that forms an abelian extension of a BMS-like algebra with a higher-spin supertranslation sector when restricted to specific symmetry generators on the sphere at null infinity.

Self-duality of massless scalar three-point amplitudes

This paper generalizes a recent observation in $\mathcal{N}=4$ Super-Yang-Mills theory to prove that off-shell massless scalar three-point Feynman integrals are self-dual under Fourier transformation, thereby establishing their representation as graphical functions and deriving new identities for graphical functions and twist relations in $\phi^4$ theory.

Updating the holomorphic modular bootstrap

This paper updates the holomorphic modular bootstrap by incorporating exact S-matrix results to systematically classify admissible and tenable solutions for modular linear differential equations with up to six characters and effective central charge up to 24, ultimately identifying their corresponding conformal field theories and modular tensor categories.
