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 provides a complete proof of the -theorem, which asserts the monotonic decrease of charged degrees of freedom along renormalization group flows in two dimensions, by deriving a correct sum rule that incorporates partial contact terms and utilizes the positivity of the averaged null energy operator.
This paper constructs and compares an supersymmetric analog of the derivative expansion of the bosonic membrane action with the static-gauge supermembrane action, demonstrating that while the two theories are inequivalent in due to differing fermion representations, they yield identical one-loop scattering amplitudes in the special dimensions and $5$.
This paper establishes a Hirota-tau and Heun-function framework for a modified affine Toda model to demonstrate that fermion-soliton interactions, governed by one-loop quantum corrections and a deformed Noether-topological current, yield stable kink configurations with a complete scattering spectrum that has implications for topologically protected states in quantum and condensed-matter systems.
This paper presents a more realistic formulation of Abbott et al.'s analysis by demonstrating that sequential quantum measurements, modeled via Gaussian wave packets, fundamentally alter the fractal geometry of particle paths by shifting the Hausdorff dimension, with nonselective evolution reducing roughness and selective evolution requiring feedback control to stabilize trajectories.
This study demonstrates that Rastall gravity offers a viable phenomenological framework for mitigating the hydrostatic mass bias in galaxy clusters by effectively aligning hydrostatic mass estimates with observed baryonic or lensing masses, although it does not universally outperform other modified gravity models under standard statistical criteria.
This paper derives the Polyakov loop kinetic term from first principles in SU(3) Yang-Mills theory and demonstrates that while this term drastically alters gravitational-wave predictions for confinement transitions, it has a negligible impact on chiral transition dynamics within the PNJL framework.
This paper presents a numerical solution to the Quantum Spectral Curve for strings on AdSST with R--R charge, revealing a spectrum that transitions from a nearest-neighbour Bethe Ansatz description at weak coupling to flat-space string mass levels with universal scaling and Kaluza-Klein splitting at strong coupling.
This paper presents an analytical study of shear mode transport coefficients in asymptotically anti-de Sitter black branes, deriving explicit expressions for SYM up to order and generalizing the results to dimensions by characterizing the solutions in terms of multiple polylogarithms.
This paper proposes a non-minimally coupled running curvaton model that successfully accommodates DESI's preference for dynamical dark energy with phantom crossing while preserving early-universe predictions and potentially alleviating the Hubble tension.
This paper demonstrates that in Doubly Special Relativity, both local modified dispersion relations and rainbow-metric approaches yield a universal near-horizon black-hole temperature scaling determined solely by the ratio of deformation functions , with corrections becoming significant only in the Planck regime.
