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 presents a theoretical framework comparing electromagnetic radiation signatures from scalar fields in modified gravity with those of axion-like particles, demonstrating how distinct parity couplings and resonance effects can produce observable differences to aid in distinguishing between these models.
This paper proposes an Orthonormal Completeness Hypothesis to demonstrate that interactions between different Kaluza-Klein modes are universally present in brane-world models, offering a potential theoretical explanation for phenomena like flavor mixing that were previously overlooked due to the assumption of non-interacting modes.
This paper presents a Lagrangian geometric formulation of non-relativistic quantum mechanics using bundle geometry, where the Schrödinger equation and path integral arise naturally from a covariant derivative and action functional, and which is further reformulated into a relational framework via the dressing field method to treat particle positions as physical reference frames.
This paper analyzes the structure of edge partition functions for massive and massless totally symmetric tensors on , revealing that the edge contribution for linearized Einstein gravity arises from shift-symmetric vector and scalar fields on , which suggests an interpretation involving an embedded brane.
This paper investigates the effects of rotation on QCD phase transitions using a Polyakov-enhanced linear sigma model, revealing that while the model successfully describes mechanical properties and satisfies the Tolman-Ehrenfest law in the large-volume limit, it predicts a decrease in critical temperatures with increasing rotation that contradicts first-principle lattice results.
This paper investigates interacting scalar field theories with anisotropic sound speeds, deriving exact elastic unitarity relations that induce - mixing, verifying the anisotropic optical theorem, and analyzing how anisotropy modifies the effective potential and renormalization group flow, particularly in the context of radiatively generated masses.
This paper demonstrates that in dynamical Chern-Simons gravity, the parity-odd trispectrum of curvature perturbations is not an independent observable but can be fully expressed as a rational, factorized "double copy" of the parity-odd graviton power spectrum and the mixed inflaton-graviton bispectrum.
This paper demonstrates that the one-loop graviton path integral on factorizes into a bulk thermal partition function and an edge contribution involving massless shift-symmetric fields, revealing that graviton edge partition functions probe beyond the horizon's intrinsic geometry and providing a compact formula for the integral on any Einstein manifold.
This paper employs a hydrodynamic framework to demonstrate that while linearized temperature correlations in a homogeneous active nematic remain unaffected by activity, spontaneous flow transitions in confined systems generate distinctive inhomogeneous temperature profiles that serve as a thermal signature of activity.
This paper introduces a novel method for generating infinite sequences of quasi-isospectral higher-order Hamiltonians by reversing the conventional Lax pair interpretation to treat the higher-order -operator as the starting point, utilizing intertwining techniques to derive new integrable systems from known solutions like those of the KdV equation.
