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 path integral ambiguity of the IKKT matrix model by deriving a Minkowskian Nambu-Goto-type formulation for perturbative closed superstrings that realizes "stringy causality," which is then used to construct a corresponding Minkowskian NBI-type matrix model via matrix regularization.
This paper presents a covariant quantization of the first-order Einstein-Hilbert theory using path integral and BV formalisms, demonstrating the closure of the gauge algebra, deriving a novel trivial local symmetry, and establishing the quantum equivalence between first- and second-order formulations at the level of the effective action.
This paper presents a minimal basis for non-derivative baryon-number-violating operators in the Standard Model Effective Field Theory up to mass dimension 11, as well as specific dimension-12 operators, offering a set of terms that generally features fewer components and simpler contractions than existing results while acknowledging cases where minimality conflicts with structural simplicity.
This paper analyzes nonabelian surface holonomy on a bipartite hypercubic lattice, demonstrating how the lattice's bipartite structure facilitates the introduction of spike string configurations that are essential for describing time evolution when the total number of color indices changes.
This paper investigates the dynamics of massive test particles and high-frequency quasi-periodic oscillations (HF QPOs) around a static black hole in nonlocal gravity, demonstrating that the nonlocal parameter enhances the effective potential and radiative efficiency while reducing the ISCO radius, and subsequently constrains the nonlocal parameter to and the black hole mass to based on QPO resonance models and observational data.
This paper establishes a connection between leading singularities and canonical bases for Feynman integrals beyond polylogarithms by demonstrating that selecting integrals with unit leading singularities necessitates introducing new transcendental functions related to geometric periods, which satisfy -factorized differential equations and correspond to a specific decomposition of the period matrix.
This paper demonstrates that Lyapunov exponents serve as robust probes for the thermodynamic phase structure of four-dimensional Horava-Lifshitz black holes, exhibiting multivalued behavior and a mean-field critical exponent during first-order phase transitions while also revealing generic violations of the chaos bound within thermodynamically stable phases.
This article proposes a framework to solve the inverse problem of identifying the ultraviolet origins of CP violation and Peccei-Quinn symmetry breaking by demonstrating that six representative classes of effective operators near the QCD scale generate distinct, experimentally distinguishable patterns of electric dipole moments across various nuclear, atomic, and molecular systems.
This paper establishes a universal topological classification of massive particle trajectories in spherically symmetric black holes, revealing that the coalescence of stable and unstable circular orbits at the ISCO critical point exhibits van der Waals-like phase transition scaling and corresponds to specific anomalous dimensions of double-twist operators in the dual CFT.
This paper proposes a pre-inflationary mechanism in a five-dimensional open FRW universe where negative curvature facilitates the dynamical stabilization of the radion via bulk quantum effects, enabling a transition to an effectively four-dimensional spacetime prior to standard inflation.
