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.

Non-Gaussian hydrodynamic fluctuations in an expanding relativistic fluid

This paper derives analytical evolution equations for two- and three-point velocity correlators in a boost-invariant relativistic fluid using effective field theory, demonstrating that the Landau frame is optimal for studying non-Gaussian fluctuations and revealing that three-point correlations exhibit nonlinear memory effects dependent on two-point dynamics, which are crucial for the search for the QCD critical point.

A perturbative Liouville prescription for the celestial three-gluon amplitude

This paper resolves ambiguities in the Stieberger-Taylor-Zhu Mellin-Liouville formulation to derive a controlled perturbative expansion of the celestial three-gluon amplitude in a dilaton background, successfully reproducing tree-level Yang-Mills results and providing a closed-form expression for one-loop corrections.

Couch-Torrence conformal inversion, supersymmetry and conserved charges for D3-branes

This paper utilizes Couch-Torrence conformal inversion to establish a precise matching between infinite towers of Newman-Penrose charges at null infinity and Aretakis charges near the horizon for D3-brane geometries in various dimensions, while further demonstrating how residual supersymmetry relates scalar charges to infinite towers of conserved asymptotic spinorial charges associated with dilatino fluctuations.

A No-Cloning Trade-off Between Black Hole No-Hair and Horizon Smoothness

This paper establishes a quantitative trade-off derived from unitarity and semiclassical assumptions, proving that any observable exterior quantum hair on a black hole necessarily implies a quantifiable violation of horizon smoothness, thereby demonstrating that the no-hair theorem and exact horizon smoothness are mutually incompatible under unitary evolution.

BV quantization of ϕ3\phi^3-theory on λ\lambda-Minkowski space: Tree-level correlation functions

This paper reviews the Batalin–Vilkovisky quantization of ϕ3\phi^3-theory on λ\lambda-Minkowski space by comparing standard and braided approaches, demonstrating that while standard quantization produces two inequivalent classes of tree-level diagrams with distinct noncommutative contributions, braided quantization yields a single class of diagrams where noncommutativity manifests only as an overall phase factor dependent on external momenta.

Shadow of the Scalar Hairy Black Hole with Inverted Higgs Potential

This paper investigates the optical appearance and shadow characteristics of scalar hairy black holes with an inverted Higgs potential using ray-tracing and thin accretion disk models, revealing that while increasing the scalar field at the horizon enlarges the shadow and disk size, the brightness remains similar to Schwarzschild black holes, allowing for potential mimicry and enabling constraints on the potential parameter Λ\Lambda using M87 and Sgr A* observations.
