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 interprets multiway gravitational junctions in AdS as interfaces between holographic conformal theories, demonstrating that their linearized scattering is governed by universal quantum maps factorizing into a tension-dependent scattering matrix and Virasoro automorphisms driven by stringy modes.
This paper introduces a generalized matrix model on a D-dimensional Euclidean space that serves as a non-perturbative definition of discretized closed and open-closed string theories, demonstrating that its free energy corresponds to the Einstein-Hilbert action with a cosmological constant and Yang-Mills terms, where the gravitational and cosmological constants are explicitly determined by graph invariants without requiring on-shell metric conditions.
This paper introduces a Super-Grassmannian formalism for to $4$ three-dimensional superconformal field theories that makes super-conformal and -symmetry constraints manifest, successfully reproducing AdS correlators and demonstrating a direct connection to flat-space SYM scattering amplitudes through a specific CPT self-conjugate super-operator construction.
This paper reviews the historical decline and subsequent revival of Weyl gauge theory, presenting it as a unique, anomaly-free spacetime gauge theory with a physical gauge boson that naturally generates the Einstein-Hilbert action and a positive cosmological constant through spontaneous symmetry breaking, while also introducing a more fundamental Weyl-Dirac-Born-Infeld action that eliminates the need for UV regularization.
This paper presents leading-order calculations for forward trijet production in the gluon-initiated channel of proton-nucleus collisions within the Color Glass Condensate framework, identifying specific contributions from four-gluon vertices and rapidity/collinear divergences to validate the dilute-dense hybrid formalism as a crucial step toward complete next-to-leading order analyses.
Using the fuzzy-sphere approach, large-scale exact diagonalization, and density-matrix renormalization group methods, this study demonstrates that spin- impurities coupled to the -dimensional Wilson-Fisher CFT flow to distinct stable infrared conformal fixed points for each , a phenomenon termed "fortuitous universality."
This paper investigates the Kaluza-Klein compactification of Hull's generalized Sen action for self-dual fields on generic manifolds, demonstrating that a consistent truncation requires including zero-modes from both metric-induced towers to avoid a naive doubling of massless degrees of freedom, while also identifying a natural deformation involving an additional form-field that introduces no new on-shell degrees of freedom.
This paper establishes the uniqueness of the known ghost-free multi-spin-2 theory by proving that its specific coupling structure is the only possible configuration for genuine multi-field interactions involving more than two vielbeins, while also demonstrating that more general interactions remain ghost-free if they are constructed from tree-structured graphs of these fundamental potentials.
This paper investigates the vacuum-induced current density of a charged scalar field in a -dimensional cosmic dispiration spacetime threaded by a magnetic flux, demonstrating that the helical geometry of the defect generates both azimuthal and axial current components that are periodic in the magnetic flux and significantly influenced by the screw dislocation parameter.
This paper formulates a fluctuating hydrodynamics with spin that is both generally covariant and pseudo-gauge invariant by extending the Gaussian covariant approach using torsion as an auxiliary field and deriving second-order gravitational Ward identities in the torsionful case.
