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.

Non-local gravity effects in cosmological dynamics probed by IceCube/KM3NeT signals and dark matter relic abundance

This paper investigates how non-local gravity models, reduced to scalar-tensor theories via Noether symmetries, can simultaneously explain the high-energy astrophysical neutrino fluxes observed by IceCube/KM3NeT and the cosmological abundance of dark matter through a specific four-dimensional operator.

Thermodynamics and Geometrical Optics of Reissner Nordstrom de Sitter Black Holes in Noncommutative Geometry

This paper investigates the thermodynamic, optical, and dynamical properties of Reissner-Nordstrom-de Sitter black holes in noncommutative spacetime, revealing how a minimal length scale induces a second-order phase transition, modifies gravitational lensing, and systematically impacts orbital instability and quasinormal modes under a lukewarm horizon condition.

Extending the Euler-Heisenberg action to include effects of local Lorentz-symmetry violating backgrounds

This paper computes Lorentz-symmetry violating corrections to the Euler-Heisenberg effective action using the spectral regularization method within the Standard Model Extension, revealing second-order Furry's theorem violations, emergent axion-like terms, and spacetime-dependent dispersion relations that induce wave amplification or attenuation due to energy-momentum exchange with the background.
