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 demonstrates that a novel first-order action functional consistently incorporates gravity and matter fields, offering a robust new pathway toward the unification of fundamental interactions within a more fundamental theory of General Relativity and the Standard Model.
This paper demonstrates that nonlocal modifications to General Relativity, specifically an Infinite Derivative Gravity model of the Ricci scalar without a cosmological constant or scalar fields, can dynamically explain the Universe's accelerated expansion and offers a technique to derive verifiable predictions such as a decreasing effective gravitational constant.
This paper proposes that Einstein-Cartan gravity emerges from the spontaneous symmetry breaking of a pre-geometric SO(1,4) or SO(3,2) gauge theory via a Higgs-like mechanism, thereby deriving fundamental concepts like the metric, diffeomorphism invariance, and the equivalence principle while offering a potentially renormalizable path to the ultraviolet completion of gravity.
This paper demonstrates that nonlocal gravitational interactions, specifically within Infinite Derivative Gravity theories, can circumvent the Weinberg no-go theorem to explain cosmic acceleration and the cosmological constant without requiring fine-tuning or additional matter fields.
This paper introduces a model for continuous tensor categories as algebra objects in the Morita bicategory of -algebras, generalizing Tambara-Yamagami categories to locally compact abelian groups and classifying them via continuous symmetric nondegenerate bicharacters and a sign, while proving that -tensor categories satisfying Tambara-Yamagami fusion rules inherently possess continuous associators.
This paper proposes a reformulated swap approach to the minimal string/matrix model duality that resolves previous conceptual difficulties by eliminating the need for resonance transformations and enabling a new conjecture for computing non-tachyon amplitudes.
This paper argues that the Generalized and Extended Uncertainty Principles are effective descriptions of non-local gravitational interactions in Infinite Derivative Gravity, using their comparison with non-local black hole solutions to derive theoretical constraints on free parameters and establish universal laws for black hole physics beyond General Relativity.
This paper constructs a comprehensive atlas of simple gauge theories with massless fermions based on ab-initio assumptions, utilizing a degree-of-freedom counting method to identify the SU(5) Georgi-Glashow model as the minimal Grand-unification Theory for three matter generations and to map out viable extensions of the Standard Model.
This paper investigates the stabilizer complexity of Hawking radiation by calculating Wigner negativity in various black hole evaporation models, demonstrating that it remains low before the Page transition but grows exponentially afterward, and proposing a geometric formula linking this complexity to the presence of a "python's lunch" in the entanglement wedge.
This paper investigates the gradient property of renormalization group flows in scalar-fermion quantum field theories up to four-loop order, demonstrating that the beta shift is essential for satisfying over a thousand scheme-independent gradient conditions and that conformal field theories with non-zero beta shifts dominate the theory space as the number of fields increases.
