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.
This paper resolves the puzzle of black hole-induced vacuum decay by demonstrating that while small black holes can initially generate highly-boosted true vacuum bubbles, radiative dissipative losses inevitably decelerate them, ensuring the decay rate remains exponentially suppressed rather than runaway.
This paper proposes a unified resolution to the cosmological constant problem by integrating holographic naturalness and pre-geometric gravity, arguing that the stability of the de Sitter vacuum arises from an entropic barrier linked to a pre-geometric Higgs field that dynamically generates both spacetime geometry and the observed smallness of dark energy.
This paper demonstrates that the logarithmic modes in critical topologically massive gravity arise from a unipotent monodromy action on the space of linearized solutions, a geometric structure that uniquely determines the characteristic logarithmic form and mixing of two-point functions without relying on prior logarithmic conformal field theory assumptions.
This paper proposes that a transient phase of enhanced parity violation during inflation, modeled by a time-localized Chern–Simons coupling, generates a distinctively blue-sloped, highly polarized primordial gravitational wave background that could explain recent pulsar timing array signals while distinguishing them from astrophysical origins.
This paper demonstrates that incorporating fractional memory effects and angular dynamics into the study of cosmic string loops in an expanding universe reveals a class of stable, expanding solutions and chaotic behavior that contrasts with the standard collapse scenario.
This article demonstrates that extending the standard model of cosmology with self-interacting dark radiation and a running spectral index function during inflation significantly relaxes constraints on additional relativistic degrees of freedom and reduces the Hubble tension to below 2 when confronted with data from ACT DR6, Planck, DESI DR2, and Pantheon+.
This paper investigates the integrability of a spinning scalar probe in a root-Kerr background, demonstrating that while the Newman-Janis shift preserves integrability to all spin orders at leading charge interaction, integrability breaks down at the spin-cubic order for second-order charge interactions and cannot be restored by further action deformations.
This paper demonstrates that in two-dimensional evaporating black hole models, increasing the black hole scrambling time suppresses and eventually eliminates late-time entanglement revival spikes in mutual information, marking a smooth transition from quasiparticle-like behavior to maximal scrambling.
This paper demonstrates that the mathematical constant emerges from equatorial quantum localization on a sphere via a geometric rigidity index that yields exact Wallis partial products for finite quantum numbers and converges to the classical Wallis formula in the semiclassical limit.
This paper utilizes the heat kernel formalism and analytic continuation from a product of spheres to derive two-point correlation functions for heavy scalar fields in Nariai geometry, revealing that the result requires a sum over complex geodesics where careful phase management is essential to prevent spurious singularities.
