3464 papers
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.
Clothed particle representation in quantum field theory: Fermion mass renormalization due to vector boson exchange
This paper employs the method of unitary clothing transformations to derive particle-momentum-independent fermion mass renormalization due to vector boson exchange in mesodynamics and quantum electrodynamics, successfully eliminating mass counterterms and contact terms while confirming consistency with standard Feynman techniques.
New quasi-Einstein metrics on a two-sphere
The paper classifies all axis-symmetric non-gradient -quasi-Einstein structures on a two-sphere, identifying the extreme Kerr black hole horizon as a specific case and providing new regular metrics for other values of expressed via hypergeometric functions.
Entanglement Harvesting and Quantum Discord of Alpha Vacua in de Sitter Space
This paper investigates the quantum information properties of -vacua in de Sitter space by using Unruh-DeWitt detectors to show that entanglement harvesting and quantum discord exhibit distinct behaviors for time-like and space-like separations, specifically demonstrating "sudden death" for time-like entanglement and superhorizon suppression for quantum discord.
Well-posedness of minimal dRGT massive gravity
The authors demonstrate that the minimal dRGT massive gravity theory can be formulated as a strongly hyperbolic first-order system around a Minkowski background, suggesting that its Cauchy evolution is well-posed despite its usual interpretation as a low-energy effective field theory.
Resurgence of the Tilted Cusp Anomalous Dimension
The High-Temperature Limit of the SM(EFT)
This paper derives the one-loop effective 3-dimensional Lagrangian for the high-temperature limit of the electroweak theory and the Standard Model effective field theory up to , providing a precise framework for studying the electroweak phase transition.
Scheme Dependence of the One-Loop Domain Wall Tension
This paper demonstrates that two recently developed methods for calculating the one-loop domain wall tension in the 3+1 dimensional model yield consistent results when the same renormalization scheme is applied.
