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 establishes a method to compute cosmological correlators in de Sitter space by relating their energy discontinuities to unitarity cuts of flat-space scattering amplitudes via auxiliary propagators, thereby enabling the reconstruction of these observables through dispersion relations and sum rules.
This paper presents a unified category-theoretic framework that describes the transition between quantum Hall hierarchy states and anyon superconductivity through a generalized stack-and-condense procedure, successfully reproducing known phases and predicting novel charge-$ke$ anyon superconductors derived from fractional quantum Hall states.
This paper explicitly derives global conformal blocks on the torus in a special necklace channel under specific conformal dimension constraints and verifies that these functions satisfy previously established Casimir equations.
This paper proposes that the existence of a second, confining vacuum in quantum Yang-Mills theory, characterized by a non-zero eigenvalue of an auxiliary field, fundamentally alters correlation functions to vanish at large spacelike distances, thereby providing a mechanism for confinement that may underpin both the measurement process in quantum mechanics and the emergence of conscious states.
This paper proposes that dark energy emerges naturally from a topological mechanism involving massless chiral spinors and harmonic 1-forms in spacetimes with internal boundaries, which induce contortion terms in the Einstein-Cartan action that mimic General Relativity with a cosmological constant.
This paper argues that the Unruh effect must be incorporated into the theoretical framework of uniformly accelerated observers in the Minkowski vacuum to correctly recover classical Larmor radiation, thereby suggesting that the observation of such radiation serves as indirect evidence for the Unruh effect.
This paper investigates the moduli space of multi-fractional instantons on a twisted by demonstrating that 't Hooft's constant field strength solutions constitute the entire moduli space only when , whereas for , they represent a measure-zero subset surrounded by non-constant, non-abelian solutions, a finding that resolves a recent puzzle and is validated through analytical, numerical, and lattice comparisons.
This paper utilizes an open quantum system formalism to calculate the inflaton four-point correlation function in axion inflation, demonstrating that the derived parity-odd expansion coefficients in the large limit not only confirm parity violation but also align with recent observational data from galaxy surveys.
This paper investigates how theoretical priors and the choice of parametrisation significantly influence observational constraints on dark energy and modified gravity, comparing phenomenological and effective field theory approaches to distinguish physical models from unphysical ones.
While shift-symmetric Horndeski and generalized Proca theories struggle to accommodate the phantom-divide crossing suggested by DESI, CMB, and SN Ia data without theoretical pathologies, the authors demonstrate that breaking shift symmetry in Horndeski theories enables a stable model with a scalar potential and Galileon interactions that successfully realizes this transition at low redshifts.
