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 constructs and analyzes the scattering diagram for BPS states on local by combining insights from orbifold and large volume limits to map the physical stability slice and provide evidence for the Split Attractor Flow Tree Conjecture within a specific range of central charge phases.
This paper rigorously derives the physical gauge group of Yang-Mills theory as the quotient of boundary-preserving gauge transformations by Gauss law transformations by analyzing the structure of the instantaneous state space, and extends this analysis to demonstrate how boundary conditions and the resulting gauge group differ between the unbroken and broken phases of Yang-Mills-Higgs theory.
This paper demonstrates that sustaining a constant electric field in de Sitter space necessitates a tachyonic photon mass, which, when incorporated into an on-shell renormalization scheme, resolves previous infrared divergences by yielding a finite, positive Schwinger current for both charged fermions and scalars.
This paper investigates the dynamics of Loschmidt echoes in noisy quantum many-body systems by establishing an equivalence to dissipative operator norms, proposing a universal two-regime decay model (Gaussian for weak noise and exponential for strong noise) linked to operator growth, and rigorously validating these findings using a solvable chaotic circuit.
This paper explicitly calculates the regulator-dependent parameters for three-loop gauge -functions in supersymmetric theories using exponential higher covariant derivative regularization, providing closed-form expressions and demonstrating how finite coupling redefinitions restore the Novikov–Shifman–Vainshtein–Zakharov relation.
This paper resolves thermodynamic ambiguities in four-dimensional charged de Sitter black holes by adopting a Bousso-Hawking normalization relative to a freely-falling observer, revealing that while the near-extremal Nariai limit avoids a breakdown of the semi-classical description due to finite heat capacity, fundamental statistical limitations persist in the cold and ultracold regimes where the heat capacity vanishes.
This paper extends a previously developed generally covariant formalism to incorporate the diffusion of conserved charges, while clarifying the apparent distinction between chemical potential and diffusion terms.
This paper constructs a nonperturbative Kontorovitch-Lebedev-Fourier (KLF) momentum space for quantum field theory on de Sitter spacetime, where the dS frequency serves as a unitary representation label, thereby transforming equations of motion into algebraic forms and streamlining the computation of in-in correlators and loop integrals through a group-theoretical framework.
This study demonstrates that the carrier-envelope phase and pulse shape of asymmetric electric fields significantly influence electron-positron pair production, with specific configurations capable of enhancing pair density by two to three orders of magnitude through multiphoton dominance and optimized envelope steepness.
This paper investigates conformal quantum mechanics by analyzing perturbative ultraviolet divergences in multi-dimensional -matrices and deriving exact, infinite-series results for the beta function of the inverse square potential in one dimension across both bound and scattering sectors.
