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 a microscopic model of the dark sector based on Hot New Early Dark Energy (Hot NEDE) and spontaneous symmetry breaking, which introduces a dark radiation matter decoupling mechanism to resolve the Hubble tension by aligning cosmological data with the SH0ES determination at a 1.4 level.
This paper demonstrates that the proper time renormalization group flow, despite not being an exact functional equation, correctly reproduces the universal one- and two-loop -function coefficients and anomalous dimensions for both scalar and Yang-Mills theories, thereby validating its reliability for capturing essential renormalization content across diverse physical applications.
This paper presents a fully covariant Quantum-Molecular Dynamics framework for relativistic N-body systems interacting via scalar and vector potentials, deriving exact equations of motion to resolve fundamental issues regarding time constraints, non-relativistic limits, and frame independence while offering new insights through scattering analyses.
This paper investigates the relativistic 3D weak-neutral axial-vector and spin distributions in nucleons, demonstrating that the conventional axial radius is physically meaningless while defining a genuine 3D spin radius dependent on the induced pseudoscalar form factor, and provides corresponding cross-section formulas to guide future neutrino-scattering experiments.
This paper presents a complete group-theoretical derivation of Nielsen's quantum complexity for unitaries in oscillator group representations by explicitly solving geodesic equations under right-invariant metrics and expressing the resulting complexity in terms of solutions to a transcendental equation.
This paper utilizes the holographic product formula to derive general expressions for holographic spectral functions in the near-extremal hydrodynamic regime, demonstrating how low-temperature gapless modes and IR conformal behavior factorize to improve the description of low-energy dynamics.
This paper analyzes the dynamical content of rank-two covariant derivatives in the Coxeter HS model within by classifying primary fields and gauge-invariant operators, demonstrating that one-forms encode symmetric massless and partially massless fields of all spins and depths, and studying the gluing of these one-form modules to zero-form modules at linear vertices.
This paper evaluates local metric-source responses in celestial Einstein scattering using Weyl--Beltrami variables to establish integrable completions, derive Ward responses and soft theorems for various helicity configurations, and extract anomaly functionals and Euler coefficients from scalar sector calculations.
This paper derives a generalized entropy formula for topological tensor networks that accommodates infinite particle-like excitations in theories with non-compact gauge groups, interpreting SL(2,R) networks as models of three-dimensional gravity with small Newton's constant.
This paper derives terrestrial constraints on Majorana bulk neutrinos within the Dark Dimension scenario by analyzing their mass spectrum and mixing, demonstrating that KATRIN beta-decay data provides the strongest limits on Yukawa couplings while the Kaluza-Klein tower effectively screens neutrinoless double beta decay signals.
