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 investigates a cosmological inflation model combining the Einstein-Hilbert action, Higgs potential, and a Gauss-Bonnet term with dilaton-like coupling, demonstrating through numerical analysis that the resulting inflationary observables align well with recent ACT DR6 data, whereas the model without the Gauss-Bonnet term reverts to chaotic inflation predictions.
This paper constructs a novel family of exact five-dimensional rotating Lifshitz black holes supported by electric and axionic charges, verifies their thermodynamic consistency, and demonstrates how rotation and the dynamical critical exponent influence holographic superconductivity in the dual system.
This paper presents a Palatini Supergravity model of induced-gravity Higgs inflation that is consistent with ACT DR6 data, successfully generates the parameter and non-thermal leptogenesis within a B-L MSSM extension, and predicts a split SUSY scenario with a PeV-scale gravitino mass compatible with LHC Higgs mass constraints.
This paper demonstrates that the quantized Chern-Simons couplings in three-dimensional F-theory compactifications provide a scheme-independent, one-loop exact encoding of all four-dimensional abelian anomalies and their Green-Schwarz cancellation, a result derived by matching flux-induced M-theory terms with explicit one-loop integrations and confirmed through compatibility with type IIB modular duality.
This paper proposes that the concept of Quasilocal Probability in curved spacetime induces horizon-driven non-Hermitian dynamics in black hole ringdowns, producing a unique, correlated set of observational signatures that can be distinguished from generic modified gravity effects and tested with upcoming gravitational wave data to probe the fundamental nature of quantum mechanical Hermiticity.
The paper introduces SubTropica, a Mathematica package that utilizes tropical geometry to symbolically integrate multi-polylogarithmic integrals like Feynman diagrams, alongside its independent HyperIntica engine and an AI-driven online library for cataloging and retrieving physics results.
This paper establishes a dual 3D Einstein-de Sitter gravity interpretation for the soft reparametrization mode of double-scaled SYK, demonstrating that the system's effective action, junction conditions, and entropy precisely match those derived from a 2+1-dimensional gravitational model with specific conformal boundary conditions.
This paper derives exact expressions for the factors in the Hadamard form of the retarded Green function for the Teukolsky equation on Schwarzschild spacetime by utilizing a conformal direct-product metric to obtain a separable direct part and its multipolar modes, ultimately providing an improved representation of the Green function near coincidence for gravitational perturbations.
This paper investigates the late-time evolution of an anisotropic Bianchi-I universe containing radiation and electromagnetic fields within asymptotically safe gravity, revealing that quantum effects soften anisotropy in radiation-dominated scenarios while the presence of a cosmological constant ultimately drives the universe toward an isotropic de Sitter phase, whereas its absence leads to a persistent Kasner-type anisotropic regime.
This paper investigates how quantum entanglement and Bell-inequality violations in top-antitop pair production at future lepton colliders serve as sensitive probes for distinguishing the Standard Model from new physics scenarios involving scalar mediators, bosons, and Kaluza-Klein gravitons.
