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.

Gravitational form factors of the nucleon in the Skyrme model based on scale-invariant chiral perturbation theory

This paper investigates the role of the QCD scale anomaly in the nucleon's gravitational form factors using a scale-invariant Skyrme model, demonstrating that the inclusion of a scalar meson to represent gluonic contributions is crucial for satisfying nucleon stability conditions and accurately reproducing lattice QCD results for the D(t)D(t) form factor.

Traversable Wormhole Solutions in massive F(T)F(T) gravity

This paper presents exact, horizonless traversable wormhole solutions in massive F(T)F(T) gravity by combining a perturbative dRGT graviton-mass term with various redshift profiles, demonstrating that the additional anisotropic pressure from the mass term can sustain the wormhole throat while satisfying or minimally violating energy conditions.

From Simulations to Surveys: Domain Adaptation for Galaxy Observations

This paper presents a domain adaptation pipeline that significantly improves the accuracy of classifying real SDSS galaxy morphologies by training on simulated TNG50 images and employing a combination of feature-level optimal transport losses, including a novel top-kk soft matching mechanism, to effectively bridge the simulation-to-reality gap.

Macroscopic backreaction of the trace anomaly on classical vacuum backgrounds

This paper investigates the macroscopic backreaction of quantum fields in the Boulware vacuum on Schwarzschild spacetime by applying an order-reduction procedure to the Riegert–Mottola–Vaulin renormalized stress-energy tensor derived from the conformal anomaly, while ensuring stress-energy conservation and comparing the results with recent literature.

Pseudospectrum and (in)stability of black hole total transmission modes

This paper investigates the spectral stability of total transmission modes in dd-dimensional Tangherlini black holes using pseudospectrum analysis, revealing that while these modes are generally unstable like quasinormal modes, a specific purely imaginary mode exhibits enhanced stability and that genuinely complex families emerge in dimensions d8d \geqslant 8.

On-shell representation and further instances of the 2-split behavior of amplitudes

This paper establishes on-shell representations for split tree-level scattering amplitudes across various theories and demonstrates that the 2-split behavior persists in gauge and gravity theories with higher-dimensional operators, thereby reinforcing its universal nature while generalizing transmuting operators to higher-derivative contexts.
