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 introduces a novel method utilizing new projection operators to derive the propagators for two three-dimensional electrodynamics models, followed by an analysis of their causality and unitarity.
This paper analyzes the disk path integral of timelike Liouville theory as a two-dimensional toy model for quantum cosmology, computing one-loop wavefunctions in the fixed extrinsic curvature representation, conjecturing all-loop expressions, and proposing a well-defined inner product for Euclidean histories through the pairing of these path integrals.
This paper constructs a basis of uniform-transcendental pure integrals for five-point off-shell conformal integrals in maximally supersymmetric Yang-Mills theory and computes their two-loop integrated results to provide symbol-level expressions for half-BPS correlation functions.
These lectures explore two correspondences between gauge theories and integrable many-body systems, linking gauge-theoretic dynamics to Calogero–Moser-type systems through infinite-dimensional Hamiltonian reduction and supersymmetric instanton counting, with a focus on SU(N) theories across dimensions one to six.
This paper classifies and discovers new classes of irrational fixed points in coupled Virasoro minimal models by systematically breaking the maximal permutation symmetry into various subgroups, including finite Lie-type and sporadic groups, thereby significantly expanding the known landscape of compact unitary CFTs with and only Virasoro chiral symmetry.
This paper investigates the symmetries and 't Hooft anomalies of 2+1d lattice staggered fermions on sheared tori and Klein bottles, establishing a nontrivial mapping between lattice and continuum symmetries to successfully match their anomalies while developing a general formalism for Hamiltonian lattice models on compact flat spaces.
This paper introduces the concept of "diabolical critical points" as higher-codimension topological defects in phase diagrams where equilibrium states exhibit non-trivial winding, demonstrating their existence in classical systems and providing conditions for their stability in (1+1)-dimensional quantum systems.
This paper demonstrates that in Weyl-invariant Einstein-Cartan gravity, assumptions regarding post-inflationary reheating temperature and the equation-of-state parameter significantly influence predicted inflationary observables, thereby necessitating their consistent inclusion in phenomenological analyses.
This paper demonstrates that the action for any system of interacting particles can be rendered invariant under gauged Galilean transformations, resulting in a complex Lagrangian but a simple Hamiltonian characterized by first-class constraints that generate the corresponding gauge symmetries.
This paper investigates spin-0, 1, and 1/2 field perturbations of four-dimensional Einstein-Skyrme anti-de Sitter black holes by computing quasinormal modes, greybody factors, and strong cosmic censorship parameters, revealing a Konoplya-Zhidenko anomaly in the first overtone and demonstrating that the Christodoulou parameter remains well below the censorship threshold due to the theory's intrinsic constraints.
