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.

Inverting no-hair theorems: How requiring General Relativity solutions restricts scalar-tensor theories

This paper investigates how imposing the existence of specific General Relativity solutions, such as Schwarzschild or de Sitter black holes with stealth scalar hair, restricts the parameter space of general quadratic and cubic scalar-tensor theories, revealing that while requiring all such solutions eliminates odd-parity deviations from GR, less restrictive scenarios allow for specific deviations, stability constraints, and modified gravitational wave speeds.
