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.

Teleparallel $F(T)$ electromagnetic static spherically symmetric spacetime solutions

This paper investigates static, spherically symmetric spacetimes in covariant teleparallel $F(T)$ gravity with electromagnetic sources, deriving field equations and conservation laws to establish a general reconstruction procedure that yields exact charged solutions—including black-hole-like and wormhole-like branches—which generalize Reissner–Nordström spacetimes and offer new insights into strong-field physics beyond General Relativity.

Linac: linear algebra with CUDA over finite fields

The paper introduces Linac, a high-performance, open-source, parallel implementation of Gaussian elimination over finite fields and floating-point arithmetic using CUDA, designed to accelerate the solution of linear systems for applications such as the analytic reconstruction of scattering amplitudes in quantum field theory.

CP conservation in the strong interactions

This paper argues that CP is conserved in strong interactions because topological quantization arises from taking the infinite spacetime volume limit before summing over topological sectors, a reasoning the authors demonstrate is consistent with steepest-descent path integral constructions and robust against various objections regarding theta-parameters and instanton approximations.

Probing Black Hole Phase Transitions through Quasi-Periodic Oscillations

This theoretical study investigates the potential link between black hole quasi-periodic oscillations (QPOs) and thermodynamic phase transitions by analyzing how QPO frequencies vary with Hawking temperature in RN AdS and Kerr black hole backgrounds, suggesting that while observational data is currently lacking, changes in black hole geometry may influence QPO behavior.

Anatomy of the simplest renormalon

This paper demonstrates that the simplest infrared renormalon, identified in the ground state energy of a two-dimensional scalar $O(N)$ theory with negative squared mass, correctly reproduces the asymptotic expansion of the exact large $N$ solution and allows for the explicit determination of the complete trans-series of non-perturbative corrections for both the energy and the two-point function.

Inflationary models in a minimally coupled $f(R,T)$ gravity: Constraints from $Planck$, BICEP/$Keck$, and ACT

This paper investigates the viability of mutated hilltop, D-brane, and Woods-Saxon inflationary models within a minimally coupled $f(R,T)$ gravity framework, demonstrating that specific parameter spaces for these models can satisfy current observational constraints from Planck, BICEP/Keck, DESI, and ACT.

Central Charges and Vacuum Moduli of 2d $\mathcal{N}=(0,4)$ Theories from Class $\mathcal{S}$

This paper investigates 2d $\mathcal{N}=(0,4)$ theories derived from 4d $\mathcal{N}=2$ class $\mathcal{S}$ theories by proposing conjectural formulas for their central charges and validating them through a Lagrangian analysis of vacuum moduli spaces for $SU(2)$ gauge groups.

Note on higher spins and holographic symmetry algebra

This paper extends the holographic symmetry algebra for gravitons and gluons by demonstrating that conformally soft higher spin particles generate a $w_{\infty}$ subalgebra (and an $S$ -algebra for colored particles) that does not commute with the standard $w_{1+\infty}$ subalgebra, a result verified via tree-level MHV amplitudes and extended to non-zero cosmological constants.

Constraining Black Hole Parameters in Non-Commutative Geometry using Machine Learning

This paper employs CUDA-accelerated machine learning to constrain non-commutative black hole parameters by analyzing shadow behaviors and energy emission rates, ultimately demonstrating that the proposed model is consistent with Event Horizon Telescope observations of the $SgrA^*$ black hole.

Scale-Invariant Open Quantum Systems

This paper establishes a comprehensive theoretical framework for open quantum systems coupled to scale-invariant "unparticle" environments, deriving exact non-Markovian dynamics and identifying a rich phase structure of decoherence and thermalization transitions governed by the scaling dimension $d_{\mathcal{U}}$ , with applications ranging from critical quantum magnets and inflationary cosmology to high-energy astrophysical neutrinos.
