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 Koopman-Krylov framework based on the Koopman-von Neumann description and gEDMD approximation to characterize non-integrable semiclassical string dynamics, demonstrating how integrability-breaking deformations induce observable-dependent delocalization and spectral weight redistribution in Krylov space.
This paper establishes that general actions for extended objects depending on both worldvolume and induced metrics are classically equivalent to the Nambu-Goto action, demonstrating that volume-preserving diffeomorphism symmetry is as physically constraining as full diffeomorphism symmetry across Riemannian, areal, and volume-metric spacetimes.
This paper investigates Maxwell electrodynamics with an additive CPT-even Lorentz-violating term by deriving modified conservation laws and analyzing the resulting corrections to the Compton effect.
This paper investigates an acoustic black hole within Hayward spacetime derived from relativistic Gross-Pitaevskii theory, numerically analyzing its shadow, quasinormal modes, and analogue Hawking radiation to demonstrate how a tuning parameter enhances emission rates and shadow size while stabilizing oscillation frequencies through effective potential modifications.
This paper proposes a class of models based on a gauged flavor symmetry that simultaneously explains the fermion mass hierarchy via the Froggatt-Nielsen mechanism and solves the strong CP problem with a high-quality axion, while also providing a unified framework for dark matter, leptogenesis, and testable flavor-changing predictions.
This paper investigates the analytical dynamics of spinning particles in pp-wave spacetimes, including plane gravitational and impulsive shockwaves, by utilizing specific spin supplementary conditions and Hamiltonian formalisms to establish a relationship between these motions and electromagnetic fields via gauge-gravity duality.
This paper develops a formalism for calculating the finite, observer-dependent quantum effective potential in dimensional Euclidean Rindler space and applies it to demonstrate the restoration of spontaneously broken symmetry in three and four dimensions.
This paper derives the probability for chiral oscillation of Majorana neutrinos within quantum field theory by utilizing the Bogoliubov transformation to relate lepton number eigenstates at different times, thereby characterizing the time variation of lepton number as a transition amplitude.
This paper extends the decomposition conjecture to two-dimensional quantum field theories with gauged symmetries involving Hopf algebras by explicitly computing partition functions and topological operators to verify the theory and formulate a generalized conjecture for non-group-associated Hopf algebras.
Using worldline quantum field theory and modern diagrammatic techniques, this paper derives spinning black hole scattering trajectories up to quadratic order in spins and establishes a new framework for computing radiated angular momentum up to 2PM order, thereby advancing high-precision analytical gravitational wave physics.
