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 utilizes gauge-gravity duality to characterize the low-energy dynamics of systems with higher-form symmetries, revealing how double-trace deformations and bulk masses induce distinct hydrodynamic and quasihydrodynamic regimes constrained by pole collisions, emergent symmetries, and novel strong/weak dualities.
This paper demonstrates that non-trivial stringy excitations and self-contained clocks can emerge dynamically in three-dimensional de Sitter space through gravitational junctions and memory effects, governed by Nambu-Goto and Nambu-Goto-Monge-Ampère equations without requiring external observers.
This paper investigates how dynamic mass variations and the presence of a stable photon sphere near extremal black holes alter orbital periapsis shifts, demonstrating that these qualitative changes in strong-field orbital behavior serve as a viable experimental probe for the Weak Gravity Conjecture.
This paper proposes a Hamiltonian formalism for gravitational dynamics in a coherent state basis that describes how non-orthogonal quasiclassical geometries evolve into superpositions, offering a mechanism for geometry tunneling and suggesting a path to preserving unitarity during black hole evaporation through quantum corrections.
This paper provides a semi-analytic study of the Nariai limit in Kerr-de Sitter and Myers-Perry black holes to demonstrate that massive scalar field quasinormal modes form an exceptional line in parameter space, leading to unique excitation phenomena such as destructive interference and transient linear growth near these double-pole frequencies.
This paper derives a family of integrable reflection matrices for excitations scattering off a boundary with a degree of freedom by utilizing symmetry and boundary Yangian invariance, and concretely applies these results to 1/2 BPS Wilson loops in ABJM theory to identify boundary bound states and verify them perturbatively.
This paper investigates a dyonic Kalb-Ramond black hole pierced by a cloud of strings within Lorentz-violating gravity, utilizing MCMC analysis of twin-peak QPOs and EHT shadow data to constrain its parameters while comprehensively mapping its geodesic dynamics, thermodynamic properties, and radiative observables.
This paper introduces a "spectral dispersion" bootstrap strategy that combines de Sitter spectral decomposition with dispersion relations to efficiently compute loop-level cosmological correlators by reconstructing them from on-shell nonlocal signals and quasinormal modes.
This paper demonstrates that thermal effects in a minimal one-scale dark-sector gauge theory significantly alter the decay dynamics of metastable -strings by favoring thermally induced nucleation over zero-temperature monopole nucleation, thereby shifting the viable parameter space for explaining the nanohertz gravitational wave background observed by Pulsar Timing Arrays toward lower dark fine-structure constants and higher monopole-to-string-tension ratios.
This paper proposes a fixed-order perturbative on-shell construction of scattering amplitudes using BCFW-generated trees and integrated vacuum pairs, successfully reproducing the known one- and two-loop all-plus four-gluon amplitudes up to order through a polygon-organized inclusion-exclusion framework.
