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.

Dynamical Formation of Charged Wormholes

This paper constructs static, spherically symmetric, charged traversable wormhole solutions supported by negative-energy null dust and proposes a dynamical formation scenario where a black hole evolves into a wormhole through sequential transitions mediated by impulsive null shells, with the resulting throat radius determined by the initial black hole's and injected shell's mass and charge.

On Lagrangian formulations for (ir)reducible mixed-antisymmetric higher integer spin fields in Minkowski spaces

This paper extends Lagrangian formulations to construct gauge-invariant descriptions for (ir)reducible integer higher-spin massless and massive fields with mixed-antisymmetric symmetry in dd-dimensional Minkowski space using BRST methods, while also proposing a deformation procedure for their interacting models.

Light Vector Dark Matter via a Magnetic Dipole Portal: Bridging Direct Detection and Fixed-Target Searches

This paper proposes a sub-GeV vector dark matter model mediated by a magnetic dipole portal arising from a broken non-Abelian SU(2)DSU(2)_D symmetry, demonstrating that a significant parameter space consistent with thermal relic abundance and current constraints remains viable and highlights the necessity of combining fixed-target, direct detection, and cosmological searches for comprehensive discovery.

Linear realization of SU(3) parity doublet model for octet baryons with bad diquark

This paper constructs a linear SU(3)L×SU(3)RSU(3)_L \times SU(3)_R parity doublet model for octet baryons that, by incorporating the (3,6)+(6,3)(3,6) + (6,3) representation containing "bad" diquarks alongside the dominant (3,3ˉ)+(3ˉ,3)(3,\bar{3}) + (\bar{3},3) representation, successfully reproduces the ground-state mass hierarchy (including the Σ\Sigma-Ξ\Xi ordering) and predicts the spectrum of excited states up to 2.5 GeV.
