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 introduces a modification of QCD sum rules using Euclidean time correlators in coordinate space instead of Borel transforms, demonstrating that while nucleon mass and residue can be roughly estimated, this approach suffers from significantly larger uncertainties and a lack of a stable working window compared to traditional Borel sum rules.
This paper presents the leading-color two-loop QCD corrections for Higgs-plus-two-jet production in the heavy-top limit, providing analytic expressions for finite helicity amplitudes derived via numerical unitarity and a novel partial fraction decomposition algorithm, alongside a stable numerical implementation and an analysis of their singularity structure.
This paper generalizes a previously proposed knot-cabling approach for constructing two-qubit entangling gates in SU(2) topological quantum computers to the SU(N) case, while analyzing the specific differences and new challenges that arise in this broader framework.
This paper employs Landau singularity analysis within the Schwinger-Keldysh effective field theory framework to systematically identify frequency-space singularities induced by nonlinear interactions, thereby determining the power-law late-time relaxation modes of gapless fluctuations without explicitly performing loop integrations.
This paper utilizes the AdS/CFT correspondence to derive higher-dimensional generalizations of BPZ null-state equations from a light scalar field in a black hole background, confirming previously proposed four-dimensional results and extending them to regimes beyond the near-lightcone limit.
This article generalizes unifying relations for tree-level amplitudes to the one-loop level by constructing differential operators via the CHY formula that transform gravitational Feynman integrands into those of various theories, thereby establishing a unified network of one-loop interactions that factorizes into tree-level operators under unitarity cuts.
This paper derives the fundamental BCJ relation for bi-adjoint scalar tree amplitudes using soft theorems, extends this relation to one-loop Feynman integrands, and applies it to explain Adler's zero in non-linear Sigma and Born-Infeld theories.
This article presents a state-independent quotient procedure on the Cayley graph of the Clifford group to construct reduced graphs that precisely map the orbits of both stabilizer and non-stabilizer states under Clifford gate actions, thereby generalizing earlier reachability results and yielding deeper insights into state evolution.
This paper utilizes the universality of single soft behavior and the double copy structure to fully determine tree-level non-linear sigma model amplitudes via an expanded formula relating them to bi-adjoint scalar amplitudes, while also deriving the corresponding double soft factors.
This paper employs a bottom-up method based on soft theorems to recursively construct single-trace Yang-Mills-scalar amplitudes with manifest gauge invariance and permutation symmetry, yielding results equivalent to those derived via covariant color-kinematic duality.
