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 summarizes a presentation on the moduli-dependent Species Scale in Quantum Gravity, demonstrating how it governs the differential equations of one-loop Wilson coefficients for BPS operators and generates a one-loop potential that stabilizes Kähler moduli at "desert points" in Type IIB orientifolds.
This paper establishes a quantitative trade-off derived from unitarity and semiclassical assumptions, proving that any observable exterior quantum hair on a black hole necessarily implies a quantifiable violation of horizon smoothness, thereby demonstrating that the no-hair theorem and exact horizon smoothness are mutually incompatible under unitary evolution.
This paper reviews the Batalin–Vilkovisky quantization of -theory on -Minkowski space by comparing standard and braided approaches, demonstrating that while standard quantization produces two inequivalent classes of tree-level diagrams with distinct noncommutative contributions, braided quantization yields a single class of diagrams where noncommutativity manifests only as an overall phase factor dependent on external momenta.
This paper demonstrates that the zero-mass limit of the partition function for covariant locally localized gravity on a Karch-Randall braneworld yields a theory containing a massless graviton and a decoupled massive vector, rather than the standard Randall-Sundrum II model, by deriving a fully covariant description to compute the one-loop partition function.
This paper investigates the optical appearance and shadow characteristics of scalar hairy black holes with an inverted Higgs potential using ray-tracing and thin accretion disk models, revealing that while increasing the scalar field at the horizon enlarges the shadow and disk size, the brightness remains similar to Schwarzschild black holes, allowing for potential mimicry and enabling constraints on the potential parameter using M87 and Sgr A* observations.
This contribution develops a multi-parametric formalism inspired by vacuum perturbation theory to model the orbital evolution and gravitational wave emission of asymmetric compact binary systems in realistic astrophysical matter distributions by reducing the complex dynamics to wave equations resembling the vacuum case.
This work assesses the sensitivity of the upcoming gamma-ray missions COSI and AMEGO-X to sub-GeV fermionic dark matter in vector-scalar portal models and demonstrates that COSI can provide leading constraints on gamma-ray lines beyond CMB limits, while AMEGO-X can probe most of the viable parameter space for continuous gamma rays.
This contribution presents a theory-independent, geometric analysis of the interior of Schwarzschild black holes, demonstrating that dynamical evolution generically produces new singularities absent in static configurations, thereby imposing stringent constraints on gravitational collapse.
The work constructs a stable solution of a type-3 electric flux tube in SU(3) gauge theory with fundamental scalar fields that resists Schwinger pair production, while noting the failure to construct a corresponding type-8 solution.
This paper demonstrates through time-domain simulations that the nonlinear scalar ergoregion instability on horizonless spinning ultracompact spacetimes saturates via a weakly turbulent direct cascade, which rapidly transfers energy to small scales and populates the stable light ring with higher-order modes, suggesting similar turbulent mechanisms will shape gravitational wave signatures in fully gravitational scenarios.
