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 paper argues that while a finite-dimensional quantum model of de Sitter space is inherently ambiguous due to measurement limitations, a precise mathematical description of our universe might still be achievable if it can be embedded within a sequence of models converging to a unique superstring theory in asymptotically flat space.
This paper challenges the conventional wisdom that decelerated expansion precludes event horizons and accelerated expansion precludes particle horizons by demonstrating, through regular bouncing cosmological models, that the existence of these non-local horizons depends on the spacetime's complete past and future history rather than just its instantaneous expansion phase.
This paper argues that Euclidean wormholes offer a physically rich and holographically consistent alternative to the Hartle-Hawking no-boundary proposal for defining the Universe's initial quantum state, successfully expanding the semiclassical landscape of initial conditions while resolving key issues plaguing earlier models.
This paper provides a detailed classical analysis of a "metric-affine-like" generalization of Yang-Mills theory (mal-YM) where the connection is not Hermitian-compatible, introducing non-trivially interacting fields that form a non-Abelian Stückelberg theory which becomes massive via spontaneous symmetry breaking and recovers standard Yang-Mills theory in the infinite mass limit.
This paper extends the optical metric method for gravitational lensing to a static optical constant-curvature (SOCC) background, demonstrating that the exact lens equation retains a unified trigonometric form and successfully resolves the divergence of the light deflection angle in the zero-mass limit of Weyl gravity's Mannheim-Kazanas solution by properly incorporating long-distance curvature effects.
This paper demonstrates that incorporating a time-dependent torsion scalar into a non-interacting holographic dark energy model with the Hubble radius as an infrared cut-off successfully drives cosmic acceleration and yields an equation of state distinct from the cosmological constant, thereby resolving limitations found in earlier interacting models.
This paper proposes a model of holographic dark matter derived from the infrared horizon cutoff rather than particle physics, which successfully accounts for dark matter density, explains the baryon-dark matter coincidence, and reverses the sign of a negative vacuum energy to match observational requirements.
This paper proposes that sums over gauge group representations of half-BPS Wilson loops in multiple copies of super Yang-Mills create entangled states dual to "bubbling wormhole" geometries—multi-covers of AdS with intersecting boundary spheres—by correlating matrix model eigenvalues in a manner analogous to the thermofield double state.
This paper presents a novel exact solution to the Einstein-scalar-Maxwell equations describing a dynamical black hole immersed in a time-dependent electromagnetic field, which generalizes the Fisher-Janis-Newman-Winicour solution within the Fonarev framework and demonstrates how time dependence can cloak curvature singularities that would otherwise be naked in stationary limits.
This paper proposes a unified framework to constrain negative masses by identifying unique gravitational-wave signatures—such as anti-chirps, dispersal, and runaway motion—that are absent in current observations, thereby providing a robust exclusion channel independent of modified gravity assumptions.
