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.

Black bounce as a quantum correction from string T-duality: Thermodynamics, energy conditions, and observational imprints from EHT

Motivated by string T-duality, this paper constructs a nonsingular "black bounce" spacetime that interpolates between regular black holes and traversable wormholes, demonstrating its thermodynamic stability, phase transitions, and consistency with Event Horizon Telescope observations while identifying the specific energy conditions violated by the underlying effective fluid.

The continuum spectrum of nonrelativistic multi-frequency Proca stars

This paper presents a systematic study of the continuum spectrum of spherical multi-frequency Proca stars, demonstrating that they interpolate between discrete stationary states and that a subset of these configurations are linearly stable, with potential implications for determining particle spin in ultralight dark matter models.

Hamiltonian Lattice QED3_3 with One and Two Flavors of Wilson Fermions: Topological Structure and Response

This paper resolves the inability of staggered-fermion discretizations to support topological phases in (2+1)D Hamiltonian lattice QED3_3 by demonstrating that Wilson fermions naturally enable nontrivial topological regimes with nonzero Chern numbers, which are characterized through gauge-invariant diagnostics and exact diagonalization to provide a foundation for near-term quantum simulations.
