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 that a modified post-inflationary expansion history can simultaneously suppress the tensor-to-scalar ratio and render relic gravitons invisible in the aHz range while allowing for a potentially detectable high-frequency signal and satisfying constraints from large-scale magnetism.
This paper demonstrates that supertranslations, traditionally defined as asymptotic symmetries at spacetime boundaries, can be naturally extended into the bulk as coordinate-independent transitions between families of null hypersurfaces, unifying their realization across different scales and revealing a novel curvature-dependent gravitational wave memory effect with observable consequences for light propagation.
This paper extends the decomposition of cyclic products of fermion correlation functions in genus two by utilizing a framework with a branch point fixed at infinity to express these products in terms of genus two theta functions for up to four points, while deriving trilinear relations from differential equations and outlining a method for the six-point case.
This paper presents an exact black hole solution immersed in a King (2,3,0) dark matter halo derived from Einstein's field equations, demonstrating that the surrounding halo significantly alters photon trajectories, gravitational lensing, quasinormal modes, and thermodynamic stability compared to the vacuum Schwarzschild case.
This paper introduces a novel Kerr-Hernquist black hole solution embedded in a dark matter halo and demonstrates that the halo preserves the hydrogen-like structure of quasibound states while significantly altering scalar cloud formation, instability growth rates, and superradiant amplification through density-dependent corrections.
This paper proposes a minimal high-quality QCD axion model where the Peccei-Quinn symmetry arises as a gauge-origin boundary remnant of five-dimensional invariance, allowing the axion to be a Wilson-line phase that retains exponential quality protection without requiring bulk QCD, warping, or color Chern-Simons terms.
This paper demonstrates that intrinsic conformal structures, specifically conformal embeddings and topological defect lines, enable exact solutions for the dynamics of open quantum systems in (1+1)D conformal field theories by organizing the Lindbladian evolution into solvable hierarchies and diagonal sectors.
This paper introduces the "Seesaw Reheating" scenario, where an inflaton transfers energy to a long-lived intermediate scalar associated with lepton number breaking, thereby linking the reheating temperature to neutrino mass generation and sterile-neutrino dark matter through a distinct thermal history characterized by relativistic time dilation and a relativistic-to-non-relativistic transition.
This paper demonstrates that while anomaly-mediated supersymmetry breaking (AMSB) coupled to gauge theories preserves supersymmetry perturbatively, nonperturbative instanton effects lead to complete supersymmetry breaking in the infrared, resulting in a vacuum structure that differs from its analog and undergoes a subtle, non-phase-transition shift in field configuration as the SUSY-breaking scale crosses the strong coupling scale.
This paper proposes that primordial black holes can undergo significant mass growth through neutrino absorption during the radiation era, a mechanism that alters their predicted mass distribution, shifts thermal history peaks, and modifies their potential contribution to dark matter.
