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.

Thermodynamic phase structure and topological charge of Hayward-AdS black holes under phase space constraints

This paper investigates the thermodynamic phase structure and topological charge of Hayward-AdS black holes, demonstrating that imposing a constraint to regularize the geometry not only preserves Van der Waals-type criticality but also induces a qualitative transformation in the thermodynamic configuration space, evidenced by a shift in topological charge from $-1$ to +1+1.

Effective Potential in Subleading Logarithmic Approximation in Arbitrary Non-renormalizable Scalar Field Theory

This paper extends a previously developed approach for calculating quantum corrections to the effective potential in arbitrary scalar field theories from the leading to the next-to-leading logarithmic approximation by constructing recurrence relations and renormalization group equations based on the Bogoliubov-Parasiuk-Hepp-Zimmerman procedure, a formalism applicable to both renormalizable and non-renormalizable models and verified against standard results.

Two-point functions in boundary loop models

This paper employs conformal bootstrap techniques to derive analytical expressions for two-point functions of bulk fields in critical loop models on the upper-half plane, specifically determining two-point connectivities for the Fortuin-Kasteleyn random cluster model under free and wired boundary conditions and validating these continuum predictions against lattice numerics through universal amplitude ratios.

Extending the Cosmological Collider: New Scaling Regimes and Constraints from BOSS

This paper proposes a new class of primordial non-Gaussianity arising from direct inflaton couplings that exhibit hybrid light-heavy field characteristics, leading to oscillatory modulations in the galaxy power spectrum which are analyzed using BOSS DR12 data to establish the first constraints on this extended parameter space while demonstrating enhanced sensitivity for future surveys.

On the structure of compact strong HKT manifolds

This paper investigates the geometry of compact strong HKT and BHE manifolds by proving that those with full holonomy are Kähler, establishing rigidity and classification results for solvmanifolds, and demonstrating that compact, simply connected, 8-dimensional strong HKT manifolds are Hopf fibrations over 4-dimensional orbifolds via the analysis of Ricci foliation.
