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 presents a solution for achieving fully automated, process-independent precision for future lepton colliders by utilizing the Yennie-Frautschi-Suura theorem to combine local infrared subtraction with all-order resummation of soft and soft-collinear logarithms.
This work demonstrates that in composite gravity models in the infrared regime, dynamical tensor fields with finite kinetic terms emerge via the functional renormalization group flow, reproducing the transverse-traceless sector of the diffeomorphism-invariant Einstein-Hilbert action, while longitudinal and trace contributions remain uninterpreted as gauge-fixing artifacts.
This paper investigates a renormalization-group improved Schwarzschild black hole, analyzing its horizon structure, shadow, quasinormal modes, and thermodynamic properties to demonstrate that it remains the most Schwarzschild-like regular black hole while exhibiting a Davies-type phase transition and near-marginal violations of Strong Cosmic Censorship at its inner Cauchy horizon.
This paper systematically investigates the Euclidean path integral of AdS3 supergravity at low temperatures, clarifying the role of boundary conditions and quantum fluctuations to demonstrate that the near-horizon gravitational path integral is quantum mechanically inequivalent to that of the BTZ black hole, thereby refining the distinction between near-extremal and near-BPS limits.
This paper presents a generalized method of extremal flows with discontinuities to upgrade low-order numerical solutions for spinning modular bootstrap gap maximization to high order, demonstrating the approach's effectiveness through a successful small-scale prototype.
This paper employs fuzzy sphere regularisation combined with exact diagonalisation and density matrix renormalisation group methods to successfully isolate the cubic critical point of Heisenberg magnets and accurately determine its scaling dimensions, thereby resolving the numerical challenges posed by its proximity to the model.
This paper derives a general formula for tree-level three-gluon scattering amplitudes in global de Sitter spacetime using the SO(1,4) angular momentum basis, expressing the results in terms of Wigner 3j symbols and intertwiner integrals of harmonic one-forms on the three-sphere.
This paper presents a unified framework for studying Anderson localization on the hyperbolic plane by deriving a two-parameter flow that interpolates between low- and high-dimensional behaviors, revealing an extended critical line separating metallic and insulating phases.
This paper establishes the equivalence between Ruhl's analytic definition of Toller matrices and the Feynman prescription in causal spinfoams, demonstrating that these objects can be represented as integrals over boost eigenvalues that reproduce the Wick rotation between Euclidean and Lorentzian spinfoam models.
This paper introduces the foundational principles of Physics-Informed Neural Networks (PINNs) and demonstrates their suitability for solving differential geometry problems by framing geometric constructions as loss-minimization tasks, illustrated through summaries of three related works.
