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.

Circular orbits in spherically symmetric spacetimes and BSW effect with nonzero force

This paper develops a general framework for analyzing circular particle orbits under arbitrary external forces in static spherically symmetric spacetimes, revealing that such forces can induce new stable orbit branches and near-horizon trajectories in extremal black holes, thereby enabling high-energy collisions with behavior analogous to the BSW effect in rotating black holes.

EVERY CFT3_3 HAS AN LΛw1+ \mathcal{L}_{\Lambda}w_{1+\infty} SYMMETRY

This paper demonstrates that all three-dimensional conformal field theories (CFT3_3s), including those dual to quantum gravity in AdS4_4, possess an LΛw1+\mathcal{L}_{\Lambda}w_{1+\infty} symmetry generated by the ANEC operator and its descendants, thereby extending previously known tree-level soft symmetry results to the strongly-coupled quantum regime.

Lattice Studies of Two-Dimensional Maximally Supersymmetric Yang--Mills Theory for Tests of Gauge--Gravity Duality

This paper presents ongoing lattice studies of two-dimensional maximally supersymmetric Yang-Mills theory, including the construction of a supersymmetry-preserving lattice action and the development of new simulation routines, to facilitate numerical tests of gauge-gravity duality and explore non-perturbative phenomena.

T-dualities and scale-separated AdS3_3 in massless IIA on (X6×S1)/Z2(X_6 \times S^1)/\mathbb{Z}_2

This paper constructs scale-separated AdS3_3 flux vacua in massless type IIA string theory on a (X6×S1)/Z2(X_6 \times S^1)/\mathbb{Z}_2 background by performing a double T-duality on massive IIA solutions with O6-planes, thereby identifying parametric families of solutions that allow for an uplift to eleven-dimensional supergravity.
