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.

Functorial properties of Schwinger-DeWitt expansion and Mellin-Barnes representation

The paper demonstrates that integral kernels for functions of a second-order differential operator can be expanded into a functional series that separates the geometric information of the operator (via standard HaMiDeW coefficients) from the specific properties of the function (via new basis and massive kernels) using Mellin–Barnes representations.

Scattering Amplitudes and Conservative Binary Dynamics at O(G5)O(G^5) without Self-Force Truncation

This paper presents a high-order calculation of the conservative radial action and scattering angle for two non-spinning bodies in general relativity up to O(G5)O(G^5), utilizing a scattering-amplitude framework and improved integration-by-parts algorithms to include second-order self-force effects without truncation.

Can Dirac neutrinos destabilize Z2\mathcal{Z}_2 domain wall network?

This paper demonstrates that if a Z2\mathcal{Z}_2 symmetry responsible for generating light Dirac neutrino masses is spontaneously broken, it can radiatively induce the explicit breaking necessary to destabilize domain wall networks, thereby creating a predictable link between the Dirac neutrino mass scale and a detectable stochastic gravitational wave signal.
