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 investigates the symmetry aspects of quantum field theory in four-dimensional de Sitter spacetime by deriving explicit transformation laws for generators on one-particle states, establishing corresponding Ward identities that constrain scattering amplitudes, and demonstrating the recovery of Poincaré algebra and flat-space limits in the high-momentum regime.
This paper resolves contradictions regarding Maldacena-Shenker-Stanford chaos-bound violations in black hole spacetimes by establishing a self-consistent framework that distinguishes between apparent violations caused by inconsistent angular momentum parameter choices and genuine physical violations arising from higher-order curvature corrections.
This paper derives a continuous family of generalized virial identities parameterized by a radial weighting exponent to systematically decompose global constraints for O() symmetric configurations, enabling the analytical verification of BPS solutions and the numerical diagnosis of core versus tail inaccuracies in non-BPS systems like bounces, vortices, and sphalerons.
This paper constructs four-dimensional de Sitter space as an excited Glauber-Sudarshan state within M-theory and its dual heterotic string theories to evade vacuum-based no-go theorems, deriving the necessary effective field theory conditions equivalent to the null energy condition and analyzing constraints from axionic cosmology.
This paper presents a lattice gauge theory formulation that successfully captures the continuum Atiyah-Patodi-Singer index for Dirac operators on domains with compact boundaries by exploiting its equivalence to the spectral flow of generalized domain-wall fermion operators, proving its validity for sufficiently small lattice spacings.
This paper proposes that in curved spacetime, probability acquires a fundamentally quasilocal character where gravitational boundaries and horizons convert global conservation into a flux balance law, inducing effective non-Hermiticity for restricted observers while preserving global unitarity and yielding observable imprints in black hole ringdowns.
This paper establishes a combinatorial framework using graph tubings to efficiently derive and solve first-order differential equations for massive cosmological correlators in de Sitter space by expressing them as twisted integrals of rational functions.
This paper proposes a new mechanism to solve the cosmological constant problem by utilizing a global constraint derived from a lapse function in a 5-dimensional anisotropic gravitational theory, which successfully cancels radiative contributions to vacuum energy at all orders while preserving 4D Lorentz invariance.
This paper establishes a rigorous, first-principles Euclidean-time prescription for calculating quantum tunnelling rates from initial states carrying conserved Noether charges, unifying direct and steadyon approaches to explain complex saddle points and extending results to systems with both charge and non-trivial energy.
This paper investigates how fluctuating domain walls in the three-dimensional Ising model modify bulk observables through an effective interaction with the lightest massive mode, identifying a controlled regime governed by a renormalized coupling and validating these universal predictions via Monte Carlo simulations.
