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.

Trivialization of the gravitational Green-Schwarz transformation in the non-relativistic limit of string theory

This paper demonstrates that the gravitational Green-Schwarz transformation becomes trivial in the non-relativistic limit of ten-dimensional heterotic supergravity by identifying a finite non-covariant $SO(8)$ symmetry and constructing a field redefinition that renders the Kalb-Ramond field invariant, thereby suggesting that anomaly cancellation becomes automatic in this regime.

Symmetrized operators or modified integration measure in Generalized Uncertainty Principle Models

This paper proposes an alternative approach to Generalized Uncertainty Principle models by symmetrizing operators instead of modifying the inner-product measure, thereby preserving standard momentum space and enabling standard position representations for eigenstates while comparing the merits of both methods.

Reduced superblocks at next-to-next-to-extremality for all maximally supersymmetric CFTs

This paper generalizes the reduced correlator formalism for maximally supersymmetric CFTs to mixed four-point functions up to next-to-next-to-extremality, deriving a recursive method to construct superconformal blocks and introducing "reduced superblocks" that unify and extend existing results across 3d, 4d, and 6d theories.

To boost or not to boost, that's the question

This paper demonstrates that in non-unitary field theories conjectured to be dual to cosmological correlators, scale invariance does not necessarily imply full conformal invariance (or bulk boost symmetry), a distinction illustrated using Einstein-Aether theory as a canonical example.

Some phenomenological aspects of a quantum-corrected Reissner-Nordström black hole: quasi-periodic oscillations, scalar perturbations and thermal fluctuations

This paper investigates the phenomenological implications of a quantum-corrected Reissner-Nordström black hole by analyzing its orbital dynamics and quasi-periodic oscillations to constrain quantum parameters via observational data, while also examining scalar perturbations, greybody factors, and logarithmic thermal corrections to its entropy.

Error correcting codes and heterotic Narain CFTs

This paper establishes a correspondence between specific error-correcting codes over finite fields and the Narain lattices of heterotic string theories by demonstrating how Construction A and its variants can generate the $E_8 \times E_8$ and Spin $(32)/\mathbb{Z}_2$ lattices, while also elucidating the relationship between such codes and NSR-fermions.

Dynamic effects of external axion fields in a system of many particles with spin

This paper presents a theoretical model describing the dynamic non-equilibrium effects of external axion and inertial fields on systems of particles with spin, proposing the use of spin and current densities for detecting axion-like dark matter through a closed set of equations that incorporate spin-rotation coupling.

The spatial Wilson loops, string breaking, and AdS/QCD

This paper utilizes gauge/string duality to investigate string breaking in spatial Wilson loops, specifically analyzing the influence of light flavors on the pseudopotential and estimating the spatial string breaking distance for $SU(3)$ gauge theory across temperatures from 0 to $3\,T_c$ .

Oscillation probabilities for a PT-symmetric non-Hermitian two-state system

This Letter presents a formulation of transition matrix elements for PT-symmetric non-Hermitian Hamiltonians that ensures positivity and perturbative unitarity by utilizing a positive-definite inner product, and demonstrates its application to two-neutrino flavor oscillations and the seesaw mechanism.

Exact 3D Conformal Blocks from Fractional Calculus

This paper establishes a novel connection between conformal blocks and fractional calculus to derive the exact three-dimensional conformal block as a product of two hypergeometric 4F3 functions, thereby rigorously proving a decade-old conjecture by Hogervorst and offering new analytical tools for the conformal bootstrap.
