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.

Greybody Factor, Resonant Frequencies, and Entropy Quantization of Charged Scalar Fields in the Kerr-EMDA Black Hole

This paper investigates charged massive scalar field perturbations on the Kerr-EMDA black hole background by deriving exact analytical solutions in terms of confluent Heun functions to determine a mass-dependent resonant frequency spectrum, a parameter-dependent entropy quantization that diverges at extremality, and the first closed-form greybody factor for this geometry, thereby revealing how electromagnetic coupling and dilaton deformation fundamentally alter the black hole's wave scattering and thermodynamic properties compared to standard Kerr and Kerr-Newman cases.

Mutual Information from Modular Flow in General CFTs

This paper establishes a new high-precision analytic approximation for the vacuum mutual information in arbitrary dd-dimensional conformal field theories by leveraging modular flow and twist operator contributions from primary fields, a method validated against known results and applied to previously unsolved cases like the d=4d=4 Maxwell field.

Self-Interaction and Galactic Magnetic Field Bounds on Millicharged Magnetic Monopole Dark Matter

This paper investigates a dark matter model consisting of millicharged magnetic monopoles from a dark U(1) sector with kinetic mixing to the Standard Model, deriving constraints on its parameters from dark matter self-interactions and the survival of galactic magnetic fields via the Parker effect across three distinct phenomenological scenarios.

On non-relativistic integrable models and 4d SCFTs

This paper establishes a correspondence between the generalized Schur indices of 4d N=2N=2 and N=1N=1 superconformal field theories and the eigenfunctions of non-relativistic integrable models, such as the elliptic Ruijsenaars-Schneider and Inozemtsev systems, thereby deriving new mathematical identities and extending these relationships to various classes of SCFTs.

No planar degeneracy for the Landau gauge quark-gluon vertex

This paper solves the Dyson-Schwinger equations for the Landau gauge quark-gluon vertex in quenched QCD to demonstrate that while its transverse form factors exhibit weak angular dependence, this does not constitute planar degeneracy, while simultaneously confirming that dynamical chiral symmetry breaking relies on a mutually generated tensor coupling and that the resulting quark propagator is consistent across different Yang-Mills solutions with poles only on the real time-like axis.

Technically Natural Suppression of Fifth Force

This paper proposes a Z2Z_2-symmetric mirror extension of the Standard Model within a bi-conformal gravity framework where spontaneous scale invariance breaking generates a light scalaron that naturally suppresses fifth-force couplings via symmetry, predicting a specific correlation between the force strength and scalar mass that aligns with next-generation experimental targets without relying on environmental screening mechanisms.

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.

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.
