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.

The phase diagram of confining holographic theories on constant curvature manifolds in the presence of a θ\theta-angle

This paper investigates the phase diagrams of confining holographic theories on constant curvature manifolds with a θ\theta-angle, revealing that negative curvature manifolds exhibit no phase transitions while positive curvature manifolds display both first and second-order phase transitions, alongside a proof of a holographic Vafa-Witten-like theorem for the θ=0\theta=0 case.

Anisotropic drag force in finite-density QGP from charged rotating 5D black holes

This paper investigates the anisotropic drag force on a heavy quark in a finite-density, rotating holographic plasma by utilizing the CCLP black hole dual, deriving exact results in the neutral limit and perturbative corrections in the charged slow-rotation regime, while demonstrating how worldsheet regularity resolves ambiguities to yield finite renormalized forces and equilibrium states.

Charged-Current Neutrino-Induced Single-Pion Production in the Superscaling Approach and Relativistic Distorted-Wave Impulse Approximation

This paper presents a detailed comparison of the SuSAv2 and RDWIA theoretical models against experimental measurements of charged-current neutrino-induced single-pion production from T2K, MINERvA, and MiniBooNE across a broad energy range, highlighting their respective approaches to modeling nuclear targets and pion production channels.

Generalized BPS magnetic monopoles in inhomogeneous Yang-Mills-Higgs models

This paper introduces a generalized non-Abelian 't~Hooft-Polyakov model for magnetic monopoles in inhomogeneous media that preserves the BPS bound through spatially dependent couplings, revealing a rich spectrum of regular solutions—including point-like, compact-core, hollow, and multi-shell structures—via both exact analytical integration and numerical methods.

Stochastic Krylov Dynamics: Revisiting Operator Growth in Open Quantum Systems

This paper demonstrates that while operator growth in closed quantum systems follows deterministic Hamiltonian flow in an emergent phase space, coupling to an environment transforms this dynamics into a stochastic process where dissipation induces diffusion and ultimately destroys the hyperbolic mechanism responsible for exponential complexity growth.

Time Like Geodesics of Regular Black Holes with Scalar Hair

This paper investigates the timelike geodesics of massive test particles in asymptotically flat regular black holes supported by a phantom scalar field, demonstrating how the scalar charge deforms orbital dynamics, modifies critical radii like the ISCO, and induces perihelion precession corrections that can be constrained by Solar System observations.

Towering Gravitons in AdS3_3/CFT2_2

This paper proposes a generalized procedure to extend the BPS spectrum of supergravitons in AdS3_3/CFT2_2 by dressing them with boundary-associated singletons to form a complete gravity-sector Hilbert space, which is explicitly constructed for the N=2N=2 D1-D5 system and shown to match the CFT spectrum up to specific energy levels that improve upon deformation, leading to a conjecture about the emergence of monotone and fortuitous Hilbert spaces.
