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.

The quantum group structure of long-range integrable deformations

This paper establishes a quantum group-theoretical framework for long-range deformations of homogeneous Yang-Baxter integrable spin chains by demonstrating that these deformations arise from a twist of the underlying algebra, resulting in a non-associative structure with a Drinfeld associator that encodes interaction terms while preserving perturbative integrability through a large associative substructure.

Constructing Bulk Topological Orders via Layered Gauging

This paper proposes a physically intuitive and versatile "layered gauging" construction that systematically generates (k+1)(k+1)-dimensional topological orders (including liquid and fracton phases) by stacking kk-dimensional quantum systems and sequentially gauging diagonal symmetries between adjacent layers, successfully demonstrating its applicability across diverse symmetry types such as conventional, higher-form, subsystem, anomalous, nonabelian, and noninvertible symmetries.

Phase-Space Contractions of Carrollian Black-Hole Thermodynamics

This paper investigates the Carrollian limits of Schwarzschild-AdS black-hole thermodynamics using covariant phase space methods, demonstrating that while the naive limit yields a degenerate sector with vanishing temperature and volume, specific scaling of the time generator and Newton constant allows for finite, non-degenerate extended first laws characterized by zero temperature and infinite entropy.

Constraints on a Light Singlet Scalar from Combined Exotic Higgs Decays

This paper investigates the phenomenology of a Standard Model extension with a light real gauge-singlet scalar, deriving analytical expressions for exotic Higgs decays to two and three scalars and establishing a global constraint that limits the scalar-Higgs mixing angle to cosθ<0.120.13\cos \theta < 0.12\text{--}0.13, thereby providing complementary bounds on the model's parameter space.

Non-Gaussian hydrodynamic fluctuations in an expanding relativistic fluid

This paper derives analytical evolution equations for two- and three-point velocity correlators in a boost-invariant relativistic fluid using effective field theory, demonstrating that the Landau frame is optimal for studying non-Gaussian fluctuations and revealing that three-point correlations exhibit nonlinear memory effects dependent on two-point dynamics, which are crucial for the search for the QCD critical point.

Couch-Torrence conformal inversion, supersymmetry and conserved charges for D3-branes

This paper utilizes Couch-Torrence conformal inversion to establish a precise matching between infinite towers of Newman-Penrose charges at null infinity and Aretakis charges near the horizon for D3-brane geometries in various dimensions, while further demonstrating how residual supersymmetry relates scalar charges to infinite towers of conserved asymptotic spinorial charges associated with dilatino fluctuations.
