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.
This paper proposes a model of holographic dark matter derived from the infrared horizon cutoff, which accounts for dark matter density, explains the coincidence between baryonic and nonbaryonic contributions, and reverses the sign of pre-existing vacuum energy to align negative theoretical predictions with positive observational values.
This paper employs a geometric framework to derive closed-form expressions for high-energy scattering amplitudes in theories with Nambu-Goldstone bosons and a Higgs-like scalar, using these results to characterize the relationship between HEFT and SMEFT and identify a dilaton-based model that offers a unique decoupling limit connecting HEFT directly to the Standard Model.
This paper provides comprehensive support material for the May 2025 Galileo Galilei Institute school, offering a pedagogical introduction to asymptotic symmetries and flat holography that covers foundational formalisms like the covariant phase space and Noether theorem, while presenting original derivations of the BMS group using Minkowski space and integral Hamiltonian generators for scalar fields on null hypersurfaces.
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.
This paper investigates the viability of non-Hermitian quantum mechanics in cosmology by extending the Wheeler-DeWitt framework and finding that observational constraints from inflation, structure growth, and cosmic flatness strongly suppress non-Hermitian effects, suggesting that Hermiticity may emerge dynamically in our universe.
This paper introduces post-Carroll transformations and their associated algebras, including the central-charge-carrying Carroll-Bargmann algebra and its conformal extension, the Carroll-Schrödinger algebra, to construct and analyze invariant field theories and their correlation functions across different dimensions.
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.
This paper introduces a Monte Carlo strategy to directly estimate partition function ratios between distinct global sectors, applying it to the critical 3D Ising model to determine the symmetry-twisted thermodynamic Casimir difference and extract CFT compactification data without relying on lattice derivatives or bulk subtractions.
This paper derives a novel, exact representation of the left-hand cut for arbitrary partial waves in scattering as an integral of right-hand cut imaginary parts, providing a systematic tool to quantify left-hand cut uncertainties in unitarization methods like the Inverse Amplitude Method and approaches.
This paper presents a vector-tensor compact object that, unlike black holes or standard exotic alternatives, exhibits purely dissipative relaxation without oscillatory ringdown due to a hidden chiral symmetry that converts perturbation dynamics into one-way transport, with black-hole behavior emerging only as these relaxation modes vanish in the high-compactness limit.
