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 continuum-extrapolated lattice simulations of hot QCD at the physical point using the complex Langevin equation to determine the equation of state at unprecedentedly high baryon densities, demonstrating controlled convergence and agreement with previous lattice and perturbative results.
This paper demonstrates that unitarity is preserved in four-dimensional quadratic gravity with a positive Weyl squared coefficient by proving that the extra spin-2 sector corresponds to a dual inverted harmonic oscillator rather than a ghost, thereby satisfying the optical theorem and ensuring renormalizability without asymptotic states.
This paper introduces a bootstrapping methodology combining Dyson-Schwinger equations and positivity constraints to efficiently approximate moments of large- random invariant tensor models, successfully validating the approach on quartic and hexic rank-three models and proposing new explicit formulae for the quartic case.
This paper establishes a direct link between the resurgence structure of the topological string and the wall-crossing of Donaldson-Thomas invariants by demonstrating that the algebra of alien derivatives is isomorphic to the Kontsevich-Soibelman Lie algebra, while providing numerical evidence of these connections through Borel analysis of the quintic and local models.
This paper fully characterizes the resurgent structure of Chern-Simons perturbation theory at the trivial flat connection for hyperbolic knot complements by introducing an extended matrix of -series that explicitly determines Stokes constants, defines Borel transforms via state-integrals, and extends key invariants like the Kashaev invariant and 3D-index.
This paper introduces a "symmetry breaking long exact sequence" (SBLES) of invertible field theories to classify symmetry breaking phases by relating the 't Hooft anomalies of localized defect excitations to the anomalies of the broken symmetry, thereby providing a new computational framework for understanding defect anomalies, higher Berry phases, and symmetry protected topological phases.
This paper develops a worldsheet formalism for fundamental strings in a critical decoupling limit of type IIA superstring theory, demonstrating that the resulting singular worldsheet topology resembles ambitwistor strings and providing a unified derivation of the duality web connecting various decoupling limits, including tensionless, Carrollian, and Spin Matrix limits.
This paper presents a general procedure for computing renormalized curvature integrals on Poincaré-Einstein manifolds, which clarifies the connection to existing Gauss-Bonnet-type formulas, identifies a specific scalar conformal invariant within them, and demonstrates that this invariant is non-unique in dimensions by constructing natural divergence terms.
This paper demonstrates that the apparent observational preference for dark energy models violating the null energy condition at high redshift is a misleading artifact of the standard - parameterization, as simple quintessence models satisfying the null energy condition for all redshifts predict the same observational signature.
This paper presents a construction of a four-dimensional spacetime from a three-dimensional contact manifold with a degenerate metric, yielding a solution to the Einstein equation for null dust and cosmic strings that is either conformally flat or of Petrov type D depending on the presence of cosmic strings.
