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.

Shear Viscosity and Electrical Conductivity of Rotating Nuclear Medium in Hadron Resonance Gas and Nambu-Jona Lasinio Models

This paper investigates how rotation influences the anisotropic shear viscosity and electrical conductivity of strongly interacting matter by employing kinetic theory within Hadron Resonance Gas and Nambu-Jona-Lasinio models, revealing that rotation suppresses chiral condensates, generates a sizable Hall-like conductivity, and reduces transport coefficients relative to isotropic cases.

Gravitational four-derivative corrections in non-relativistic heterotic supergravity and the $SO(8)$ Green-Schwarz mechanism

This paper presents the first explicit construction of four-derivative gravitational corrections in non-relativistic heterotic supergravity by extending the Bergshoeff-de Roo identification, revealing a gravitational $SO(8)$ Green-Schwarz mechanism that establishes a systematic framework for incorporating higher-curvature dynamics into these backgrounds.

M2-brane partition functions and HD supergravity from equivariant volumes

This paper establishes a holographic correspondence between M2-brane partition functions and equivariant volumes of toric Calabi-Yau manifolds, rigorously testing the conjecture by deriving a universal Airy function representation for squashed $S^3$ partition functions that incorporates finite $N$ corrections and higher-derivative supergravity effects, while demonstrating agreement with localization results across various models including ABJM theory and its generalizations.

Flavored QCD axion and Modular invariance

This paper proposes a string-derived supergravity model combining the Standard Model with gauged $U(1)_X$ and modular $SL(2,\mathbb{Z})$ symmetry, where anomaly cancellation conditions uniquely determine flavor structures and axion properties, predicting a specific axion mass and coupling while suppressing flavor-violating interactions and reproducing observed neutrino data.

Gravitational Noether-Ward identities for scalar field

This paper establishes that for Einstein's gravity coupled to a massive, non-minimally coupled quantum scalar field, each term in the equation of motion for metric perturbations and each necessary renormalization counterterm independently satisfies a Noether-Ward identity, ensuring the overall transversality of the equation regardless of the specific definition used for the metric perturbation.

Torsion-Induced Quantum Fluctuations in Metric-Affine Gravity using the Stochastic Variational Method

This review paper demonstrates that spatial torsion in Metric-Affine Gravity induces non-linear quantum fluctuations affecting spinless degrees of freedom through the Stochastic Variational Method, revealing a competitive interplay with Levi-Civita curvature and a structural parallelism with information geometry.

From Bertotti--Robinson to Vacuum: New Exact Solutions in General Relativity via Harrison and Inversion Symmetries

This paper constructs new accelerating vacuum solutions in General Relativity by applying Harrison and Inversion symmetries to electrovacuum configurations, demonstrating how external electromagnetic fields can be removed to leave non-trivial gravitational backreactions, including a new two-parameter extension of the Schwarzschild–Levi-Civita geometry and a stationary generalization.

Resolution of Black Hole Singularities in Jackiw-Teitelboim Gravity

This paper demonstrates that introducing a left confining potential in Jackiw-Teitelboim gravity not only restores the required discrete spectral statistics to resolve the black hole entropy paradox but also dynamically prevents the indefinite growth of wormhole length, thereby resolving the black hole singularity.

Modified Teukolsky formalism: Null testing and numerical benchmarking

This paper validates a modified Teukolsky framework for predicting gravitational-wave ringdown spectra in effective field theories by successfully passing two rigorous null tests and confirming consistency between two independent numerical methods, thereby establishing its reliability for future strong-field tests of General Relativity.

Klein--Gordon oscillator with linear--fractional deformed Casimirs in doubly special relativity

This paper investigates the Klein-Gordon oscillator within a doubly special relativity framework featuring linear-fractional deformed Casimirs, deriving exact spectra and eigensolutions for timelike, spacelike, and lightlike deformations while establishing a pseudo-Hermitian formulation and comparing the spectral shifts to the Magueijo-Smolin model.
