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.

Extended Thermodynamics and Renyi Entropy Beyond Fixed Central Charge

This paper constructs a novel central-charge Rényi entropy for thermal CFTs on a hyperbolic cylinder that satisfies fundamental entropy inequalities, revealing a characteristic index nn_* that separates the theory space into distinct statistical regimes governed by dominant CFT realizations versus fluctuating theories with higher-energy modular excitations.

Twisting Small-xx Gluon Tomography with Orbital Angular Momentum

This paper proposes an orbital-angular-momentum-resolved extension of small-xx gluon tomography in hard diffractive dijet deep inelastic scattering, demonstrating that replacing the standard plane-wave lepton current with a twisted wave-packet current enables tunable Bessel projections of the gluon Wigner distribution, thereby revealing a unique normalized projection zero where the elliptic response vanishes despite a finite diffractive rate.

Geometric and Statistical Thermo Field Dynamics in de Sitter Spacetime

This paper develops a unified Thermo Field Dynamics framework for massive scalar fields in de Sitter spacetime that integrates geometric horizon doubling with statistical thermal effects, revealing how observer-dependent perspectives (comoving vs. static) lead to distinct particle creation mechanisms and a characteristic thermal scale driven by the interplay of geometric and intrinsic temperatures.

DSWIM:Efficient and Stable Deterministic Computation of Warm Inflation Perturbations

This paper introduces DSWIM, a numerically robust and computationally efficient deterministic framework for calculating warm inflation perturbations that utilizes a physically motivated scaling transformation to resolve ill-conditioning issues, eliminate numerical artifacts, and reconcile discrepancies between stochastic and deterministic methods while preserving accuracy.

Microscopic entropy of de Sitter spacetime and entropic solution to the old cosmological constant problem

This paper proposes that the cosmological constant problem is resolved by interpreting the dimensionless coupling in conformal gravity as the Bekenstein-Hawking entropy of de Sitter spacetime, where the renormalization group flow of these microscopic degrees of freedom naturally yields the observed, extremely small value of the cosmological constant.
