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.

Neutron Star Equation of State with Nucleon Short-Range Correlations: A Concise Review and Open Issues

This concise review examines how nucleon short-range correlations and their resulting high-momentum tails modify the kinetic and interaction contributions to the neutron star equation of state, thereby influencing macroscopic observables such as mass-radius relations and tidal deformabilities, while summarizing current constraints and outlining open questions for future research.

Holographic Spread Complexity from Branes and Strings

This paper establishes a string-theoretic realization of holographic spread complexity by analyzing falling D0-branes, rotating D3-branes, and wound fundamental strings in AdS backgrounds, demonstrating that the correct short-time behavior of complexity growth is recovered by applying a Legendre-transformed Routhian prescription to account for fixed charges while distinguishing them from winding-induced effective masses.

N=1\mathcal{N}=1 spectra, cubic couplings and the rigid fate of DGKT

This paper demonstrates that in the DGKT scenario on a generic Calabi-Yau three-fold, a proposed holographic constraint on cubic couplings is satisfied if and only if the manifold is rigid (h2,1=0h^{2,1}=0), a result derived from general 4d N=1\mathcal{N}=1 supergravity relations linking extremal couplings to the superpotential's derivatives and showing that such couplings vanish in the Kähler sector but persist in the complex structure sector.

Dissipative hydrodynamic actions and horizon symmetries in gravity

This paper proposes a prescription within the Schwinger-Keldysh formalism to compute a dissipative hydrodynamic action for holographic AdS4_4 gravity by realizing hydrodynamic degrees of freedom as relative diffeomorphisms between the black hole horizon and asymptotic boundaries, explicitly deriving the action to first order in derivatives and linking horizon symmetries to conjectured hydrodynamic symmetries of quantum chaos.
