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 analyzes high-order non-abelian soft radiation data to constrain celestial holography, revealing that loop logarithms can be absorbed into coupling scale choices and that multiple emission currents break holomorphic factorization and associativity, thereby casting doubt on the viability of a simple logarithmic celestial theory.
This paper analyzes the structure of one-parameter subgroups of SO(3,2), identifying two new types distinct from those in SO(2,2), providing explicit examples, and situating existing conformal gravity solutions within this classification.
This paper demonstrates that in the large-party limit of topological entanglement entropy for Chern-Simons theory on torus link complements, non-Abelian contributions are suppressed, leaving an upper bound of determined solely by Abelian anyons, a result explicitly quantified for the SU(2) case.
This paper establishes a direct connection between flat-space unitarity and cosmological observables by using dressing rules to uplift Cutkosky cuts into discontinuity relations for dS/EAdS correlators, thereby providing a transparent diagrammatic derivation of cosmological cutting rules.
This paper investigates 6d D-type orbi-instanton SCFTs and their 4d class compactifications, demonstrating that only a specific subset admits a description via three untwisted punctures characterized by new and labels, while also revealing hidden Higgs branch flows that are not manifest in the puncture closures.
This paper derives exact classical and quantum solutions for a K-essence cosmological model with a negative power-law Saez-Ballester potential by utilizing a field redefinition to map the system to a known FLRW structure, revealing a late-time de Sitter expansion where the scalar field acts as a cosmic background.
This paper investigates the dynamical and scattering properties of Euler-Heisenberg black holes surrounded by perfect fluid dark matter, analyzing scalar, electromagnetic, and effective spin-2 perturbations to determine how dark matter and nonlinear electrodynamics influence quasinormal modes, greybody factors, Hawking radiation, and neutrino energy deposition.
The paper presents the dark bubble model, which leverages de Sitter swampland instabilities to explain the positive cosmological constant while predicting a micron-sized dark dimension, a weakening of gravity at micron scales (realizing the fat graviton scenario), a TeV-scale string mass, and measurable positive spatial curvature.
This paper utilizes gauge/string duality to construct conformal moments of unpolarized gluon GTMDs at strong coupling, demonstrating that these moments factorize into universal soft factors and stripped amplitudes while revealing how holographic backgrounds dictate infrared falloffs and enable a unified description of hadron tomography, rapidity evolution, and Reggeization relevant to the Electron-Ion Collider.
This review highlights recent breakthroughs in extending uncertainty-quantified *ab initio* nuclear theory to heavy and complex nuclei, demonstrating how these advances significantly reduce nuclear-physics uncertainties in interpreting dark matter direct detection experiments.
