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 the exact Onsager algebra of free lattice fermions in four-dimensional staggered, Wilson, and overlap formulations fully reproduces the chiral symmetry of the corresponding continuum theory, while revealing formulation-dependent trade-offs between the locality of algebra generators and the size of their compact subgroups.
This paper proposes a mechanism where scalar-induced mass splittings bias the relic abundances of cyclic -symmetric ultralight scalars through symmetric interactions, thereby enabling naturally varying dark matter masses without requiring asymmetric reheating or sacrificing radiative control.
This paper constructs three analytic, doubly warped, time-dependent cosmological solutions in massless type IIA supergravity that undergo Big Bang-to-Big Crunch evolution, exhibit temporary scale separation near their maximum expansion, and completely break all supersymmetry without requiring localized sources.
This paper addresses the asymptotic divergence of the axial vector propagator in the thermal AdS/QCD soft-wall model by implementing a momentum-dependent cutoff via an interior constraint approach, thereby enabling the successful calculation of electromagnetic and axial vector form factors for the transition that align moderately well with experimental and theoretical benchmarks.
This paper investigates neutrino transition polarizability within an inverse seesaw framework involving a light pseudoscalar that couples active neutrinos to heavy neutral leptons and photons, demonstrating how the resulting decay channels alter heavy neutrino lifetimes and identifying the enhanced sensitivity of displaced photon searches at facilities like DUNE, Belle II, LHCb, and FCC-ee.
This paper investigates how perturbations of topological defects by relevant holomorphic fields in two-dimensional conformal field theory lead to renormalization group flows that define a semiring homomorphism preserving functional relations between translation invariant defects and an asymptotic semiring constructed from topological defects, thereby constraining the infrared endpoints of these flows in models such as Virasoro minimal models.
This paper presents a UV-complete model in dimensions that exhibits a Berezinskii-Kosterlitz-Thouless ordered phase with algebraically decaying correlations at arbitrarily high temperatures, achieved through a perturbatively controlled effective field theory matched to lattice Monte Carlo results.
This paper investigates the relationship between relative Abelian BF torsion and knot Floer homology within the BV-BFV formalism, establishing connections to the Alexander polynomial and analyzing specific algebraic obstructions, though it concludes that a full geometric equivalence between the two frameworks remains unproven.
This paper constructs boundary conditions for two-dimensional Dirac fermions using Chern-Simons theory to characterize topological defects that preserve non-anomalous symmetries, demonstrating how such defects generate non-invertible twist lines and computing their associated physical invariants, including a novel example involving symmetry.
This paper establishes that Krylov-space operator dynamics correspond to a constant-speed trajectory on a sphere, where Hall's exact uncertainty relation lifted to Liouville space reveals that the first Lanczos coefficient governs the speed and higher coefficients dictate the curvature, thereby linking geometric properties of the amplitude vector to the saturation of quantum speed limits.
