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 computes tree-level celestial operator product expansions in a bosonic sub-sector of Berkovits-Witten conformal supergravity, revealing that while leading soft graviton currents retain standard singularity structures, subleading soft graviton currents acquire corrections consistent with a modified chiral current algebra, suggesting the dual celestial CFT preserves a non-trivial symmetry.
Using worldline effective field theory, this paper presents the first gauge-invariant computation of the long-wavelength graviton photoproduction amplitude by a Kerr-Newman black hole through , demonstrating that consistent electromagnetic interactions preserve spin gauge invariance and that the relevant Wilson coefficients are uniquely fixed by matching to the Kerr-Newman multipole moments.
This paper establishes a correspondence between free point particle dynamics on Riemannian manifolds and spin chains by utilizing the Kirillov orbit method and geometric quantization to demonstrate that the Laplace-Beltrami operator on a Lagrangian submanifold is spectrally equivalent to a spin Hamiltonian derived from the quadratic expansion of a specific Hamiltonian.
This paper introduces a partial-wave basis for five-point tree amplitudes of identical scalars to derive splitting constraints that, at low mass levels, uniquely determine five-point data from four-point coefficients and manifest hidden zeros, while revealing that higher-spin exchanges necessitate additional input for complete rigidity.
This paper investigates bound states within the Lee model of complex ghosts using canonical operator formalism, demonstrating that such states can be formed despite nontrivial complex delta functions, and briefly discusses the implications for restoring unitarity in quadratic gravity.
This paper establishes a finite-energy scattering theory for source-free Maxwell fields on slowly rotating, weakly charged Kerr-Newman black holes by decomposing the field into stationary and radiative components and proving uniform boundedness, integrated local energy decay, and asymptotic completeness for the radiative sector through a combination of geometric and analytic techniques.
This paper proposes a non-Markovian extension of the semiclassical Wheeler-DeWitt framework where causal memory kernels induce effective fractional time evolution, leading to a characteristic correction in the primordial power spectrum that primarily impacts high- CMB anisotropies and offers potential observational signatures for nonlocal quantum gravitational dynamics.
This paper investigates dynamical mass generation for fermions with and without bare mass in two-dimensional space-time coupled to a massive vector field using Schwinger-Dyson equations, revealing that purely dynamical masses originating from different bare masses converge at a specific coupling constant where a duality relation is satisfied.
This paper demonstrates that while the renormalization-group flow driven by BCS interactions induces a "drag mechanism" that pushes higher-dimensional fermionic operators toward strong coupling, it simultaneously preserves a parametric hierarchy that prevents these operators from destabilizing the infrared-stable non-Fermi-liquid fixed point in dimensions.
This paper investigates holographic entanglement entropy and complexity in Coulomb-branch geometries featuring flat-space bubbles, demonstrating that these regions correspond to a reduction in effective infrared degrees of freedom and entanglement relative to the standard vacuum.
