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 paper introduces "big axions," a novel class of axion models arising from the collective spontaneous breaking of delocalized U(1) symmetries that naturally solve the strong CP problem, accommodate diverse cosmological histories, and offer a robust dark matter candidate through a minimal viable subclass known as "little big axions."
This paper constructs a database of Coxeter symmetries arising from isomorphic flops in Calabi-Yau threefolds and demonstrates that the prepotential of Type IIA compactifications can be resummed into a decomposition of Helmholtz equation eigenfunctions, offering a convergent alternative to raw worldsheet instanton sums.
This paper demonstrates that key structural properties of cosmological correlators in (E)AdS, including cutting rules, tree theorems, BCFW recursion, and soft limits, can be systematically derived from their flat-space counterparts by representing them as flat-space amplitudes dressed with auxiliary propagators.
This paper investigates the state dynamics of flat band systems invariant under supertranslation symmetries by utilizing Krylov complexity to analyze quenches induced by Carroll-breaking perturbations, revealing how this measure resolves phase-dependent resilience and exhibits UV/IR mixing in continuum Carroll scalar field theories.
This paper proposes a concrete lattice realization of the equation of motion flow for -dimensional chiral gauge theories on a disk boundary, demonstrating how coupling the flow gauge field to fermions enables the mechanism of anomaly inflow and cancellation.
This paper implements and analyzes two distinct gauge field flow constructions—gradient flow decoupling and equation-of-motion (EOM) flow—for chiral gauge theories formulated with domain wall fermions on a lattice slab, demonstrating how these methods successfully preserve current conservation and realize anomaly inflow in the presence of background gauge fields.
This paper constructs the complete class of minimal-derivative cubic interactions for massless higher-spin gauge supermultiplets in harmonic superspace, revealing that these vertices are universally determined by gauge prepotentials coupled to conserved higher-spin supercurrents, including a novel complex principal supercurrent that generates both parity-invariant and parity-breaking interactions.
This paper introduces LACIA, a verification-driven agentic AI workflow that, in collaboration with human researchers, utilizes the Poincaré-Carrollian intertwiner to construct complete Carrollian conformal bases for massive and tachyonic particles, revealing that real mass necessitates a complex momentum shift in scattering amplitudes.
This paper investigates the optical properties of gravitating Abelian-Higgs cosmic strings, demonstrating that their finite core structure produces distinctive lensing signatures—such as triple imaging, strong demagnification, and a mass-ratio-dependent Shapiro time delay—that are absent in idealized infinitely thin string models and can reveal details about the strings' internal structure.
This paper revisits the spectrum of the bosonic ambitwistor string using momentum-space BRST cohomology to demonstrate that, while the spectrum contains the standard massless closed string fields plus an additional massless vector, the non-unitary nature of the representation prevents this vector from being interpreted as a physical Maxwell field.
