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 investigates the confinement of massive ghosts in quadratic gravity using a manifestly covariant canonical operator formalism, demonstrating that the asymptotic fields obey a dipole equation and that the resulting quantum Fock space is spanned by multipole states.
This paper establishes the foundational framework for counting surfaces on Calabi-Yau 4-folds by introducing two new types of stable pair moduli spaces, demonstrating their relationship to the Hilbert scheme via GIT wall-crossing, constructing reduced Oh-Thomas virtual cycles to prove deformation invariance, and applying these results to verify the variational Hodge conjecture for families supporting non-zero virtual cycles.
This paper extends the analysis of D4-D2-D0 indices to the case of two units of D4-brane charge, demonstrating that the resulting generating series are mock modular forms with specific shadows, a discovery that provides new boundary conditions to determine the holomorphic ambiguity of topological string amplitudes up to significantly higher genera than previously possible.
This paper demonstrates that non-invertible fusion algebras generate a distinct class of selection rules with genuine organizing power in particle physics, showcasing their ability to produce unique scattering patterns in scalar extensions and solve the doublet-triplet splitting problem in supersymmetric flipped models by forbidding the -term in ways impossible for ordinary Abelian symmetries.
This paper demonstrates that the trace-anomaly-subtracted -mass for heavy quarks is a unique, renormalon-free mass definition that can be precisely related to the pole mass via a five-loop perturbative formula and determined from lattice QCD, making it an ideal reference scheme for unifying quark mass calculations across different approaches.
This paper proves an intrinsic analogue of Hawking's rigidity theorem for extremal horizons in arbitrary dimensions, demonstrating that compact cross-sections of rotating extremal horizons satisfying the null energy condition admit a Killing vector field and, under the dominant energy condition, possess enhanced isometry groups that shift the Aretakis instability order for massless scalar fields.
This paper proposes a continuum field theory, specifically the Chern-Simons-Higgs model, to describe self-dual Higgs transitions from various non-Abelian topological orders to trivial states, offering a unified framework that generalizes the enigmatic toric code transition and conjectures an infrared duality to the 3D Ising transition for the case.
This paper extends the Symmetry Topological Field Theory (SymTFT) framework to include time-reversal symmetry by employing a symmetry-enriched approach, thereby characterizing (1+1)d gapped phases and clarifying the nature of string-order parameters and end-point charges in the presence of anti-unitary symmetries.
This paper employs the functional renormalisation group to demonstrate that the critical gauge coupling for dynamical chiral symmetry breaking depends strongly on the number of fermion flavors, suggesting a first-order quantum phase transition at that challenges the conventional Miransky/BKT scaling and walking regime scenarios.
This paper investigates how logarithmic corrections to the Bekenstein-Hawking entropy, arising from quantum gravity, modify the background of single-field slow-roll inflation and consequently shift the tilt and running of the scalar primordial spectrum as well as the tensor-to-scalar ratio and consistency relation, while preserving the standard Mukhanov-Sasaki evolution equation with a quantum-corrected effective frequency.
