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.

Holographic two-point functions of heavy operators revisited

This paper revisits the holographic computation of two-point functions for heavy 12\frac{1}{2}-BPS chiral primary operators in N=4\mathcal{N}=4 SYM by proposing new boundary terms in the D3-brane action to resolve previous ambiguities for giant gravitons and by calculating correlators for ΔN2\Delta \sim N^2 operators using the Gibbons-Hawking-York term in LLM bubbling geometries.

Anomaly-mediated Scalar Gravitational Interactions and the Coupling of Conformal Sectors

This paper investigates the anomaly-induced activation of a gauge-invariant scalar "conformalon" mode in General Relativity, demonstrating that its coupling to gravitons and gauge currents via single-graviton exchange generates Planck-suppressed, contact-like corrections to 222\to2 scattering amplitudes that exhibit a characteristic double-copy structure and align with conformal Ward identities.

Towards a formalism for ππ\pi\pi scattering from staggered lattice QCD

This paper addresses the challenges of extracting ππ\pi\pi scattering amplitudes from staggered lattice QCD by proposing two complementary approaches: calculating one-loop amplitudes using Rooted Staggered Chiral Perturbation Theory to verify quantization conditions, and generalizing the Lüscher formalism to explicitly incorporate taste-splitting and fourth-rooting effects.

Comment on "Lattice QCD constraints on the critical point from an improved precision equation of state"

This paper critiques a recent lattice QCD study that claims to exclude a QCD critical endpoint below μB450\mu_B \approx 450 MeV, arguing that the entropy-contour method used fails to directly probe critical singularities and therefore cannot provide model-independent constraints on the critical point's location.

Entanglement in the θ\theta-vacuum

This paper computes the entanglement entropy and spectrum of the massive Schwinger model at finite θ\theta using a chirally rotated lattice Hamiltonian, revealing that the entanglement peak at θ=π\theta=\pi arises from competing electric-flux vacuum branches and demonstrating that the entanglement Hamiltonian aligns with the Bisognano--Wichmann theorem in the infrared sector.
