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 demonstrates that within Loop Quantum Cosmology, inverse volume corrections enable low-scale spontaneously broken supersymmetric and exponential inflationary potentials to align with recent Atacama Cosmology Telescope data, placing their predictions within the 68% confidence level in the plane where standard inflation models fail.
This paper establishes a systematic, all-orders perturbative map that explicitly reorganizes diagrammatic expansions of the Wavefunction of the Universe into Schwinger-Keldysh in-in correlators, thereby providing a concrete bridge between these two central frameworks for analyzing primordial cosmological observables.
This paper investigates the breakdown of the high-temperature Atick-Witten description near the supersymmetric index in Heterotic and Type II string theories, revealing that string star solutions decouple at this limit, which suggests a fundamental tension between a smooth black hole-string transition and the existence of stringy BPS two-charge black holes.
This paper presents a no-go theorem demonstrating that standard finite-width neural network ensembles cannot consistently realize either quantum or effective field theories on a computer due to failures in reflection positivity and scale separation, with only specific infinite-width limits or relaxations of finite variance and rotation invariance offering potential escapes.
This paper proves that black hole isospectrality between parity sectors arises in chiral-aligned theories when perturbations are reconstructed from complex master variables satisfying a closed linear system, a result explicitly demonstrated for subextremal Kerr–de Sitter black holes.
This paper demonstrates that neural network models with finite width generically fail to preserve fundamental properties of conventional Euclidean quantum field theories, such as reflection positivity and cluster decomposition, and explores the specific features that can or cannot be maintained at finite parameter counts.
This paper classifies the flavor textures of baryon-number-conserving dimension-six SMEFT operators under non-invertible selection rules, revealing distinct Wilson coefficient structures and flavor patterns that deviate from Minimal Flavor Violation and offer unique predictions for B-meson and charged-lepton-flavor-violating observables.
This paper investigates an open XXZ spin chain with unparallel boundary fields under a special gauge-invariant condition, demonstrating that its transfer matrix can be diagonalized via a generalized Separation of Variables approach using bases dependent on gauge parameters only through their difference, and utilizing this framework to compute elementary correlation blocks and overlaps with eigenstates of related models.
This paper investigates the thermal propagators of scalar and fermion fields within real-time formalism by introducing an arbitrary parameter to derive their momentum and mixed-space representations at finite temperature without a chemical potential.
This paper demonstrates that supersymmetric near-horizon geometries in gauged D=5 supergravity coupled to vector multiplets inherently possess a second rotational Killing field on compact horizon sections, thereby unifying known black hole solutions and explicitly characterizing two distinct sub-branches of varying moduli without assuming rotational symmetry a priori.
