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.

Weakly turbulent saturation of the nonlinear scalar ergoregion instability

This paper demonstrates through time-domain simulations that the nonlinear scalar ergoregion instability on horizonless spinning ultracompact spacetimes saturates via a weakly turbulent direct cascade, which rapidly transfers energy to small scales and populates the stable light ring with higher-order modes, suggesting similar turbulent mechanisms will shape gravitational wave signatures in fully gravitational scenarios.

The 2-Dimensional Dual of ϕ4\phi^4 in AdS3_3

This paper investigates the one-loop correlation functions of a conformally coupled ϕ4\phi^4 theory in AdS3_3 and its dual CFT2_2, demonstrating that the non-standard loop diagram can be expressed as an infinite sum of tree-level diagrams to recursively derive anomalous dimensions for all double-trace operators, with results in the tt- and uu-channels representing novel contributions to the literature.

EFT Pathways to ΔB=2|\Delta B| =2: Chiral Constructions and Phenomenology

This paper establishes a systematic effective field theory framework using chiral symmetry to connect ultraviolet ΔB=2|\Delta B|=2 interactions to low-energy hadronic observables, demonstrating that while baryon-antibaryon oscillations probe a limited subset of operators, dinucleon decay offers a broader sensitivity to previously unexplored channels and parameter space.

Lattice Topological Defects in Non-Unitary Conformal Field Theories

This paper investigates topological defects in non-unitary conformal field theories by constructing impurity models and defect operators within restricted solid-on-solid lattice systems, where numerical computations of energy spectra and thermodynamic properties are validated against analytical predictions and used to analyze renormalization group flows.
