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 develops an effective light-front mass-squared operator for quark-antiquark systems that incorporates nonperturbative QCD dynamics through a running quark mass derived from lattice-QCD-inspired propagators, applying this framework to study the structure of the pion.
This paper investigates quantum field theories with fractional kinetic terms, demonstrating that while they share a common Euclidean counterpart, they yield multiple inequivalent Minkowski formulations through different "fakeon" prescriptions that maintain perturbative unitarity and gauge invariance.
The paper proposes approximate renormalization group invariants for Yukawa couplings in supersymmetric models to analyze unification relations and demonstrates that adding exotic superfields to the MSSM can achieve third and second-generation Yukawa unification, potentially pointing toward an underlying gauge symmetry.
This paper presents an invariant characterization of the Kerr spacetime that utilizes a specific function to identify and efficiently compute the properties of spherical photon orbits and other geometrically significant surfaces, such as ergosurfaces and horizons.
The paper proposes that the complex invariant mass spectrum observed in high-energy Pb-emulsion collisions can be explained as signatures of neutral color-singlet quark matter in both its deconfined and confined QED(U(1)) phases.
This paper reviews recent developments in Batalin-Vilkovisky (BV) formalism by characterizing its mathematical structures through Q-manifolds and QP-manifolds, while demonstrating how Lie and Courant algebroids serve as key examples for constructing BV action functionals.
The paper proposes a new mass-dependent renormalization scheme based on dimensional regularization that provides smooth transitions at particle thresholds and satisfies the Appelquist-Carazzone theorem while retaining the gauge independence and advantages of minimal subtraction schemes.
The paper proposes a regularization method for divergent power sums by using fractional extensions of differential generators to construct a generalized spectral function, providing a framework that recovers Riemann zeta regularization as a special case while allowing for additional terms determined by the chosen generator.
This paper investigates the relative Lie algebra cohomology of current Lie superalgebras over a specific algebra, identifying failures in super-analogues of the Chevalley restriction theorem and the Loday–Quillen–Tsygan theorem, while proposing a quantum deformation to restore Langlands duality.
This paper utilizes the ADM formulation to perform a small- expansion of general relativity up to next-to-next-to-leading order, providing a systematic framework for constructing exact stationary vacuum solutions in both strong- and weak-gravity regimes, including corrections to Kerr and C-metric geometries.
