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 introduces a general framework for deriving linearized dispersion spectra in Lorentz boosted frames using only local rest-frame data, revealing the emergence of causality-violating "spurious modes" and establishing a direct link between mode conservation and the causality of relativistic fluid theories.
This study utilizes the extended Linear-Sigma Model to demonstrate that incorporating SU(4) quark degrees of freedom yields meson mass predictions more consistent with experimental data than SU(3) models, while revealing that although meson masses exhibit unique temperature-dependent behaviors, they generally dissolve within a similar critical temperature range, with quarkonium states remaining largely unaffected.
This paper proves that the group of topological manipulations, including fermionization and gauging, acting on two-dimensional bosonic theories with non-anomalous and time-reversal symmetries on non-orientable surfaces forms a dihedral group of order 16, a result established through Symmetry TFT and Hilbert space sector analyses.
This paper demonstrates that within the Randall-Sundrum extra-dimensional framework, where Standard Model and dark matter fields reside on the IR brane and interact via graviton and radion portals, the observed dark matter relic abundance and baryon asymmetry can be simultaneously explained through freeze-in production and TeV-scale leptogenesis, respectively, while satisfying cosmological constraints and being subject to current LHC graviton search limits.
Using the functional renormalization group, this paper demonstrates that while supersymmetry alone does not guarantee time-reversal invariance in Model A dynamics, TRI emerges as an effective large-scale symmetry and the system's non-equilibrium flow reproduces the equilibrium effective action, allowing the recovery of the Ising model's magnetization distribution.
This paper investigates the semiclassical evolution of Hawking atmospheres around evaporating anti-de Sitter black holes by combining the Parikh-Wilczek tunneling method with renormalized energy-momentum tensor calculations to reveal significant deviations from ideal blackbody behavior driven by strong backreaction effects.
This paper proposes a novel method to probe the validity limits of the semiclassical Einstein equation by constructing a controlled, analytically tractable scenario where a mixture of weak-gravity quantum states drives the system into a strong-gravity regime, allowing for a direct comparison between quantum and semiclassical predictions via a branch-degenerate observable.
This paper investigates a generalized WKB ansatz for the quantum propagator by introducing an additive exponent as a measure of quantumness, analyzing its role through the Hamilton-Jacobi equation, and exploring its application to various systems, field theories, and Hamiltonian-constrained dynamics.
This paper demonstrates that the rate at which chiral fermion localisation is lost during domain wall merging in extra-dimensional braneworlds follows a universal power law determined solely by the Jackiw-Rebbi topological index, rendering the collapse of four-dimensional Yukawa couplings insensitive to the specific microscopic scalar dynamics of the walls.
This paper investigates the thermodynamic properties, Hawking-radiation sparsity, and greybody factors of a hairy Kiselev black hole surrounded by quintessential matter, revealing how exponential hair and quintessential fields respectively govern small-scale and large-scale behaviors, induce phase transitions, and cause highly intermittent radiation emission.
