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 presents a constructive framework that elevates gauge-invariant scattering amplitudes to define quantum field theory actions by promoting color-dual numerators to operators, thereby systematically deriving gravitational effective actions from gauge-theory components and extending color-kinematics duality from amplitudes to the operator level.
This paper extends the KMOC formalism beyond large impact parameter scattering by demonstrating that soft radiative fields, specifically electromagnetic and gravitational memory, can be computed as non-perturbative inclusive observables derived from on-shell amplitudes, consistent with previous saddle-point analyses.
This paper proposes a four-dimensional gauge-gravity unification based on Yang-Mills theory where spontaneous symmetry breaking and tetrad condensation induce Einstein-Cartan gravity and generate three composite fermion families, with anomaly matching uniquely selecting to yield the chain.
This paper advances the understanding of two-dimensional quantum gravity at finite cutoff by deriving the trumpet wavefunction and an exact Riccati equation for extrinsic curvature in JT gravity, which together yield the one-loop partition function consistent with deformation and provide a framework for generalizing these results to arbitrary dilaton gravities.
This paper establishes that real observers can only resolve the imaginary phase obstructing de Sitter entropy counting if they are "gravitational observers" whose fluctuations share the negative modes of the conformal factor, as mere information-bearing capabilities are insufficient to factorize the topological sector responsible for the phase.
This paper revisits End-of-the-World singularities in dynamical cobordisms by evaluating them against established criteria, proposing a new geometric bound on Ricci scalar divergence that accommodates EFT strings and D7-branes while rejecting massive Type IIA solutions, and suggesting a finite-temperature extension of the Distance Conjecture through the analysis of black D-branes.
This paper introduces a novel numerical bootstrap framework based on moment observables that provides rigorous bounds on conformal field theory spectra, revealing new continuous families of kinks and spectral reorganizations across dimensions that are difficult to access with traditional methods.
This paper demonstrates that type IIB supergravity provides a complete holographic description of Super Yang-Mills theory compactified on a circle with specific scalar and current sources, successfully reconstructing the theory's full vacuum structure and supersymmetric moduli space through smooth AdS soliton solutions.
This paper presents a complete classification of generalized Schwarzian theories as integrals over Virasoro coadjoint orbits, demonstrating their correspondence to near-dS gravity and providing exact solutions for their oscillatory path integrals despite inherent ambiguities in defining quantum fluctuations.
This review paper synthesizes current theoretical, cosmological, astrophysical, and experimental efforts to explore the theoretically motivated meV axion mass range, highlighting the convergence of diverse approaches aimed at discovering these particles as a key probe for beyond-Standard-Model physics.
