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.

The Minimal Supersymmetric Standard Model with Non-Invertible Selection Rules

This paper proposes a Minimal Supersymmetric Standard Model framework utilizing non-invertible selection rules derived from gauging the outer automorphism of a discrete symmetry to simultaneously generate realistic fermion mass textures and suppress flavor-changing neutral currents while maintaining stability under renormalization group evolution.

Open system probes of renormalization group flow

This paper proposes using open system probes, such as a qubit coupled to a transverse-field Ising model, to characterize quantum many-body systems by mapping long-range spatial correlations onto dynamical probe correlations, thereby enabling the identification of renormalization group fixed points, scaling dimensions, and flow behaviors.

Efficient Hamiltonian Truncation: Fast Matrix Construction and Quantum Krylov Diagonalization

This paper presents a hybrid classical-quantum strategy to enhance the efficiency of Hamiltonian truncation for quantum field theories by introducing an integer partition-based basis generation, symmetry-aware sparse matrix construction, and quantum Krylov diagonalization, demonstrating significant computational gains in two-dimensional scalar and ϕ4\phi^4 models.

Dependence of Critical Exponents Accuracy on the Number of Fields in the O(N) -Invariant \phi^4 Model

By applying the entire-hypergeometric resummation algorithm to seven-loop ε\varepsilon-expansion series, this study demonstrates that the accuracy of critical exponent predictions for the O(N)O(N)-invariant ϕ4\phi^4 model significantly improves with increasing NN, achieving precision comparable to Monte Carlo and non-perturbative RG methods for large NN.
