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.

Scalar Finite-Proper-Time Field Theory as Spectral Operator Calculus

This paper formulates a finite-proper-time construction for Euclidean scalar $\lambda\phi^4$ theory using a spectral operator calculus and complete-history diagrammatics, demonstrating that the retained endpoint scale yields a finite, momentum-dependent remainder in the one-loop four-point function that cannot be eliminated by standard renormalization or field redefinitions, thereby distinguishing it from arbitrary cutoff prescriptions.

Static multipolar Einstein-vector-Gauss-Bonnet black holes

This paper constructs and analyzes static multipolar black hole solutions in Einstein-vector-Gauss-Bonnet theory with quadratic coupling, revealing that electric branches extend to large coupling values while magnetic branches exist only on finite intervals, with both sectors bifurcating from Schwarzschild black holes at discrete coupling values determined by angular multipole numbers.

Carrollian Dictionary for Massive Particles at Null Infinity

This paper constructs a Carrollian dictionary for massive one-particle states on null infinity by encoding bulk momentum through null frame projections, thereby resolving the description of massive particles without requiring their worldlines to reach null infinity and applying this framework to fix Källén–Lehmann coefficients and analyze soft theorems.

Non-unitary Haagerup-like TQFTs and RCFTs from generalized S-fold SCFTs

This paper extends the class of 3-dimensional non-unitary TQFTs and 2-dimensional non-unitary RCFTs by deriving them from generalized S-fold SCFTs via topological twist, providing explicit modular data and identifying specific instances with generalized Haagerup-Izumi modular matrices.

Squeezed quantum states and partner modes in the moving mirror model of black hole evaporation

This paper reformulates the moving mirror model of black hole evaporation using Rindler/Milne modes to naturally incorporate partner modes, attribute required approximations to mode squeezing, and reveal nontrivial quantum correlations in the radiation spectrum beyond standard thermal distributions.

Why There is No Memory Burden in Holographic Space-time Models of Black Hole Formation and Evaporation

This paper argues that Holographic Space Time models of black hole formation and evaporation do not exhibit the "memory burden" effect claimed in recent literature, as the specific definitions of energy and causality in these models, combined with Fermi's Golden Rule, prevent such macroscopic constraints on black hole lifetimes.

Connecting the tensor-categorical formulation of anyon condensation with operator algebras and entropic order parameters

This paper establishes a manifest connection between the tensor-categorical and operator-algebraic formulations of anyon condensation using Doplicher-Haag-Roberts bimodules, while naturally defining and bounding an entropic order parameter to characterize the transition.

Fortuity and fragility in supersymmetric SYK

This paper investigates the "fortuity" and "metric fragility" of BPS states in the $\mathcal{N}=2$ supersymmetric SYK model, demonstrating that while exact uplift to arbitrarily large system sizes is generally impossible, the spectrum of a specific decoder operator quantifies the cost of such uplift and reveals that generic BPS sectors exhibit chaotic statistics distinct from exactly solvable towers.

Coherent quantum geometry: de Sitter spacetime in different foliations

This paper introduces a general framework for constructing coherent quantum states of diagonalizable metrics to demonstrate that the normalizability of such states in de Sitter spacetime necessitates the use of reference frames free from coordinate singularities.

On divergences in a four-derivative scalar field theory

This paper extends the renormalization analysis of Holdom's shift-symmetric four-derivative scalar field theories to three loops, proving the all-order IR finiteness of Euclidean correlators and establishing a non-renormalization theorem that links the theory's beta function to that of an $O(2)$ -symmetric $\phi^4$ theory at negative coupling, thereby determining its renormalization group properties up to six loops.
