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 universality theorem demonstrating that the one-loop tensor mode contribution to the thermodynamic entropy of near-extremal black holes is independent of spacetime asymptotics, symmetry, and matter content, universally yielding a term and revealing the universal emergence of Schwarzian modes in dimensions four through six.
This paper proposes a novel solution to the cosmological constant problem within pre-geometric gravity, where spacetime emergence and symmetry breaking dynamically link the Gauss-Bonnet coupling to de Sitter entropy, quantizing the cosmological constant into discrete topological sectors and naturally selecting the observed vacuum state through a stabilizing potential barrier.
This paper proposes a thermal model incorporating a common local spin equilibrium for spin-1/2 and spin-1 particles to explain the simultaneous longitudinal polarization of hyperons and positive spin alignment of vector mesons in heavy-ion collisions, noting that while the model reproduces observed trends, it currently lacks full quantitative agreement with experimental data.
This paper rigorously establishes a universal lower bound on the local equilibration time of quantum many-body systems, proving that hydrodynamic behavior cannot emerge faster than a dimension-dependent fraction of the Planckian time , regardless of the underlying thermalization mechanism or microscopic details.
This study presents new constraints on a string-motivated Chameleon dark energy model, revealing a mild preference for a non-zero dark sector coupling () and weak evidence favoring the interaction over CDM when combining Planck, DESI DR2, and SH0ES data, despite the model's asymptotic return to limiting the strength of this evidence.
This paper investigates the quantum field descriptions of massive Carrollian theories, including scalar, fermion, and electrodynamics models, with a specific focus on resolving gauge-dependence issues in scalar Carrollian electrodynamics through careful gauge fixing and demonstrating the triviality of certain abelian theories due to the absence of loop corrections.
This paper constructs the canonical ensemble of a self-gravitating thin shell in anti-de Sitter space using the Euclidean path integral approach to derive its thermodynamic properties, identify a fully stable equilibrium configuration, and demonstrate a first-order phase transition to a Hawking-Page black hole phase that occurs below a maximum temperature limit.
This paper demonstrates that the gravitational Green-Schwarz transformation becomes trivial in the non-relativistic limit of ten-dimensional heterotic supergravity by identifying a finite non-covariant $SO(8)$ symmetry and constructing a field redefinition that renders the Kalb-Ramond field invariant, thereby suggesting that anomaly cancellation becomes automatic in this regime.
This paper proposes an alternative approach to Generalized Uncertainty Principle models by symmetrizing operators instead of modifying the inner-product measure, thereby preserving standard momentum space and enabling standard position representations for eigenstates while comparing the merits of both methods.
This paper generalizes the reduced correlator formalism for maximally supersymmetric CFTs to mixed four-point functions up to next-to-next-to-extremality, deriving a recursive method to construct superconformal blocks and introducing "reduced superblocks" that unify and extend existing results across 3d, 4d, and 6d theories.
