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 proposes group entropies as a unifying framework that defines universality classes of extensive entropies for strongly correlated systems, successfully deriving consistent thermodynamic laws and demonstrating that black holes naturally exhibit negative specific heat within this formalism.
This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper establishes an explicit isomorphism between the equivariant nilpotent cohomological Hall algebra of one-dimensional sheaves on a surface resolving a Kleinian singularity and a completed positive half of the affine Yangian of the corresponding ADE Lie algebra, utilizing continuity theorems for -structures and multi-parameter Yangian definitions to characterize the algebra of cohomological Hecke operators.
This paper extends the curve integral formula for calculating colored scalar scattering amplitudes to non-orientable surfaces, such as the Möbius strip, by utilizing quasi-cluster algebras and embedding techniques, while validating the construction through superstring amplitude limits and generalizing it to higher-genus non-orientable surfaces.
The paper proves that for spherically symmetric hairy black holes satisfying the weak energy condition, the ratio of the shadow radius to the horizon radius is bounded from below by , a limit that is saturated by the Schwarzschild black hole.
This white paper, produced by the EU-funded Cosmic WISPers network, reviews the theoretical motivations and ongoing searches for Weakly Interacting Slim Particles (WISPs) as dark matter candidates, while outlining a strategic roadmap to secure European leadership in this field through diverse and cost-effective experiments over the next decade.
This paper investigates cosmology in gravity by demonstrating that a thick brane's embedding in a five-dimensional bulk naturally generates an effective cosmological constant and accelerated expansion without a fundamental brane constant, offering a geometric explanation for cosmic acceleration and the smallness of the observed cosmological constant.
This paper establishes that finite non-invertible symmetries in 3+1d without topological line operators necessarily act invertibly on local operators, leading to a decomposition of general non-invertible symmetries into invertible actions and gauging interfaces, and deriving necessary conditions for such symmetries to be anomaly-free.
This paper presents the first observational constraints on Luciano-Saridakis entropic cosmology using combined background data, demonstrating that the model provides a statistically robust fit to current observations and offers a viable extension to the standard CDM model with the potential to alleviate the Hubble tension.
This paper investigates the one-dimensional Generalized Dirac Oscillator within Doubly Special Relativity frameworks, demonstrating how complexified Morse interactions yield real spectra through pseudo-Hermiticity and symmetry while revealing distinct deformation effects on the energy spectrum under Magueijo--Smolin and Amelino--Camelia prescriptions.
