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 demonstrates that in a BRST-invariant quantization of General Relativity, the bulk Hamiltonian can be expressed as a BRST-exact operator (the anticommutator of the BRST charge and the temporal ghost field), which governs time-reparameterization of physical observables without trivializing the time evolution of gravitational backgrounds or scattering amplitudes.
This paper numerically demonstrates that while spontaneous baryogenesis exhibits a cubic dependence of baryon asymmetry on the initial misalignment angle for small values, this scaling breaks down and particle production saturates as the angle approaches in Minkowski spacetime.
This paper formulates an in-in framework for strong-field QED pair creation using worldline propagators, demonstrating that in-in corrections to in-out quantities correspond to non-local interaction terms and providing an exact first-quantized definition for the creation of N-pairs through the resummation of the partition function.
This paper presents a unified computational framework using algebraic geometry and numerical topology to analyze the vacuum structure of 4-charge extremal black holes in Type IIA string theory, successfully reproducing BPS degeneracies for specific D-brane configurations and demonstrating the absence of zero-energy ground states in non-BPS systems through advanced topological regularization techniques.
This paper derives a nonlocal Time-Energy uncertainty principle and uses Thorium-229 nuclear clock data to establish conservative lower bounds on the nonlocality scale, demonstrating that nuclear clocks can probe non-Planckian nonlocality at energy scales ranging from tens of MeV to the TeV range.
This paper constructs the soft gluon light-cone wave function and the associated unitary evolution operator up to next-to-leading order in pure Yang-Mills theory within the Color Glass Condensate framework, demonstrating how diagonalizing the soft Hamiltonian cancels off-diagonal Fock sector mixing to yield a coherent background field energy proportional to the valence color charge density squared.
This paper introduces differential operators that relate higher-Wronskian-index solutions to lower-index ones, providing an efficient method to classify rational conformal field theory characters and quasi-characters across the Wronskian tower while preserving modular covariance and integrality.
This paper demonstrates that the partition function of 5D supersymmetric Yang-Mills theory on a toric Kähler surface times a circle localizes to a sum over torus-fixed points in the moduli space of semi-stable torsion-free sheaves, yielding the refined Vafa-Witten invariants (specifically the -genus) for non-even first Chern classes.
This paper investigates how Swampland Conjectures influence the preheating of string moduli by demonstrating that the refined de Sitter Conjecture's local potential curvature and the Swampland Distance Conjecture's tower of light states collectively govern resonance efficiency and instability dynamics, respectively.
This paper proposes that the Standard Model's internal symmetries arise from the nested algebraic embeddings of real numbers through complex numbers, quaternions, and octonions into a 16-dimensional algebra, where specific conditions on endomorphisms and graded structures naturally yield the known gauge groups and charge operators.
