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.

Exploring thermal order in conformal theories with multiple scalars coupled to an O(N)O(N) vector field

This paper investigates thermal order in conformal field theories with multiple scalars coupled to an O(N)O(N) vector field, demonstrating that while certain fixed points in d=4−ϵd=4-\epsilon dimensions fail to yield unitary CFTs in d=3d=3, a large-NN analysis in three dimensions reveals a conformal manifold where specific symmetry-breaking patterns lead to persistent thermal symmetry breaking for all nonzero temperatures.

Accretion, mergers, and metastability of fuzzy spheres in a three-matrix model

This paper investigates the metastability and accretion dynamics of fuzzy spheres in a three-matrix model, revealing that while single spheres are stable, concentric "onion-like" configurations become increasingly long-lived due to logarithmically growing stiffness, with transition rates quantitatively matching one-loop effective action predictions driven by sphere center fluctuations.

Perturbations and stability of black holes with static scalar hair in general GLPV theories

This paper derives the stability conditions for static, spherically symmetric black holes with scalar hair in general quartic-quintic GLPV theories, revealing that while generic non-degenerate branches are locally unstable or degenerate, specific Horndeski-compatible deformations of scalar-Gauss-Bonnet black holes can satisfy all no-ghost and gradient-stability requirements.

Logarithmic corrections to the entropy for near-extremal rotating black holes

This paper investigates logarithmic quantum corrections to the entropy of near-extremal rotating black holes in three, four, and five dimensions, focusing on rotational zero modes to confirm agreement with microscopic descriptions for BTZ black holes, identify an additional log⁡ℓ\log \ell correction by treating the cosmological constant as independent, and explicitly construct zero modes for the five-dimensional BMPV black hole to evaluate temperature-dependent entropy corrections.
