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.

A higher-derivative model predicts a smoothness vs duration relationship in head-pointing movements

This study demonstrates that a higher-derivative Pais-Uhlenbeck oscillator model successfully predicts a parabolic relationship between movement duration and smoothness in head-pointing tasks, revealing a nonlinear temporal organization modulated by direction-specific biomechanical constraints in healthy adults.

Error Threshold of SYK Codes from Strong-to-Weak Parity Symmetry Breaking

This paper investigates the information-theoretic capacity of Sachdev-Ye-Kitaev (SYK) models as approximate quantum error correction codes under decoherence, revealing that strong fermion parity symmetric noise induces a strong-to-weak spontaneous symmetry breaking transition that degrades wormhole traversability and marks a critical threshold for code performance.

Astrophysical viability of extremal black holes

This paper argues that extremal black holes are astrophysically implausible in our universe by demonstrating that Schwinger discharge imposes a mass limit exceeding 1014M10^{14} M_\odot for charged holes, Lee-Nair-Weinberg instabilities and enhanced pair production render magnetic charges cosmologically unviable, and superradiant scattering likely drains angular momentum from extremal Kerr black holes.
