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 Tachyon Chern-Simons action with a generic tachyon field, and baryons in V-QCD

This paper constructs explicit Tachyon-Chern-Simons terms in the holographic V-QCD model for generic complex tachyon fields to ensure flavor anomaly consistency, demonstrating that baryon number equals the topological instanton number and that the resulting effective pion action reproduces the chiral Lagrangian with Skyrme and Wess-Zumino-Witten terms.

Carrollian bosonic supergravity at order α\alpha' and the universal cancellation of higher-curvature divergences

This paper proves that the Carrollian limit of bosonic supergravity remains finite when including α\alpha'-corrections, establishes a universal criterion for the finiteness of higher-curvature terms, and explicitly constructs the effective action for α2\alpha'^2 and α3\alpha'^3 corrections, demonstrating that ζ(3)\zeta(3)-proportional terms do not contribute at order α3\alpha'^3.

Analytic thermal bootstrap in momentum space: From thermal OPE to QNMs

This paper establishes an analytic thermal bootstrap framework that connects ultraviolet thermal OPE data to infrared observables like quasinormal modes by constructing meromorphic completions of thermal blocks, deriving inversion formulae and sum rules, and validating these results across various theories including free models, CFTs, and N=4\mathcal{N}=4 SYM.

Split Heun functions via blown-up surface defects

This paper derives blow-up equations to resum singular instanton expansions of Nekrasov--Shatashvili functions in four-dimensional N=2\mathcal{N}=2 SU(2)\mathrm{SU}(2) gauge theories at resonant loci, thereby revealing the analytic structure of Heun functions and constructing finite periodic, antiperiodic, and logarithmic solutions that describe spectral gap edges and semisimple monodromy.

Feynman Tree Theorem and the Gelfand--Yaglom Formula

This paper presents a new diagrammatic proof of the Gelfand–Yaglom formula by applying the Feynman Tree Theorem to re-express the one-loop determinant as a sum of tree diagrams that encode the solution to the associated initial value problem, while also extending this framework to general boundary conditions and suggesting potential applications in quantum field theory.

Quantum reference frames beyond subsystems: a reconstruction and generalization of the perspective-neutral framework

This paper reconstructs and generalizes the perspective-neutral framework for quantum reference frames by extending the concept of frames from tensor factor subsystems to covariant quantum instruments, thereby providing a resource-theoretic foundation that unifies operational quantum information with internal reference frame research to explain phenomena like particle symmetrization and relational dynamics.

Spin resummation of heavy quarkonium photoproduction: from the gluonic gravitational form factors to the holographic pomeron

This paper presents a unified holographic QCD framework that resums even-spin gluonic exchanges, anchored by lattice QCD gravitational form factors, to accurately describe exclusive heavy quarkonium photoproduction across the full energy range from near-threshold to high energies while revealing the limitations of fixed-spin approximations for extracting gravitational form factors.

Monodromy, Hidden Conformal Symmetry and Soft Hair in Kerr-MOG Black Hole

This paper establishes a consistent Kerr/CFT-type holographic duality for the four-dimensional Kerr-MOG black hole by demonstrating that thermodynamic, monodromy, and soft-hair approaches yield matching CFT parameters, allowing the Cardy formula to reproduce the Bekenstein-Hawking entropy and confirming a hidden SL(2,R)L×SL(2,R)RSL(2,\mathbb{R})_L \times SL(2,\mathbb{R})_R conformal symmetry in the near-region scalar wave dynamics.
