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.
The paper argues that simultaneously preserving renormalization group invariance, Ward identities, and parton density sum rules in QCD factorization theorems necessitates that independent factorization and renormalization scales must be equal, with significant implications for phenomenological scale sensitivity, global QCD analyses, and connections to lattice QCD.
This paper proposes a chiral axion model where the QCD axion emerges as a phase of complex scalars breaking a gauged symmetry, thereby protecting axion quality and establishing a minimal coupling to Standard Model fermions that enhances the model's testability.
Using the Functional Renormalization Group with a hydrodynamical algorithm, this study investigates the (2+1)-dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field, revealing that strong magnetic fields induce magnetic catalysis and dimensional reduction while weak fields at high chemical potential produce de Haas–van Alphen oscillations and multiple first-order phase transitions alongside a shifting critical endpoint.
This paper establishes a theoretical framework linking quantum error correction and confinement by formulating decoding for homological codes via higher form gauge fields and demonstrating that conditional logical probabilities in lattice Yang-Mills theory correspond to center-twisted partition functions, thereby distinguishing between the suppression of global flux sectors and local spectral information relevant to the mass gap.
This paper establishes Ward identities and Belavin-Polyakov-Zamolodchikov differential equations for Imaginary Liouville theory, providing a foundational step toward a rigorous conformal bootstrap program for non-rational conformal field theories with central charge less than one.
This paper establishes that the category of twisted and untwisted representations of the Heisenberg conformal net forms a continuous Tambara-Yamagami category for , enabling the first explicit computation of the braided tensor category for the fixed-point net , which features irreducible representations whose tensor products decompose into direct integrals.
This paper analyzes one-loop beta functions for scalar-fermion systems in dimensions to derive universal bounds on anomalous dimensions, establish a "level" structure for fixed points, and demonstrate that stable fixed points within a given level are unique.
This memorial paper systematically reviews the legacy of Alexei Starobinsky's 1979–1980 inflation model from a modern perspective, proposing deformations for primordial black hole production, discussing quantum corrections within superstring theory and the Swampland Program, and highlighting its universal reheating mechanism.
This paper investigates the gauge algebra of closed string field theory with a focus on diffeomorphisms, demonstrating that while the superstring algebra is universal to leading order regardless of the vertex choice, the bosonic string retains off-shell dependence and that field-dependent redefinitions of gauge parameters significantly influence the algebra's structure within the framework.
This paper establishes a purely differential geometric framework demonstrating that the Gaussian curvature of unstable null orbits serves as a direct signature of black hole phase transitions, exhibiting swallowtail-like multivalued behavior during first-order transitions and heat-capacity-like divergence at second-order critical points.
