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.

Scattering Gravitons off General Spinning Compact Objects to O(G2S4)\mathcal{O}(G^2 S^4)

This paper computes the classical one-loop gravitational Compton amplitude for graviton scattering off a massive spinning compact object at the second post-Minkowskian order up to quartic spin and hexadecapolar finite-size effects, deriving the corresponding scattering phase and explicitly linking the spin-independent contribution to a massless scalar probe in a Kerr background.

Viscosity of R2R^2 Modified AdS Black Brane

This paper investigates the shear viscosity to entropy density ratio in a four-dimensional AdS black brane with a quadratic Ricci scalar correction, revealing that the ratio ηs=14π(124q)\frac{\eta}{s} = \frac{1}{4\pi}(1 - 24q) violates the universal KSS bound for positive coupling constants while raising important questions regarding the stability and causality of the dual field theory.

Diagonal boundary conditions in critical loop models

This paper utilizes analytic bootstrap methods to define and characterize diagonal boundaries in critical loop models via a complex parameter, deriving explicit formulas for disc correlation functions and demonstrating that specific parameter values yield discrete spectra of degenerate representations, while also providing a lattice interpretation where loops cannot terminate or change weight upon touching such boundaries.

Towards Worst-Case Guarantees with Scale-Aware Interpretability

This paper proposes a research agenda for "scale-aware interpretability" that adapts the renormalization framework from statistical physics to develop formal tools capable of providing worst-case guarantees on neural network behavior by explicitly tracking how features compose across different resolutions.
