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 develops a canonical Post-Newtonian Hamiltonian framework for radiating charges by integrating the Landau-Lifshitz reduced radiation reaction into the Darwin system to derive inspiral laws, and extends this formalism to charged compact binaries in Einstein-Maxwell theory to characterize the transition between electromagnetic and gravitational flux-dominated inspirals.
This paper demonstrates that in massless scalar QED, the charge associated with divergent superphaserotations vanishes to all orders in the electromagnetic coupling due to the one-loop exactness of the classical logarithmic soft photon theorem, while also showing that infrared corrections to the subleading soft charge result in a vanishing tail to the velocity kick memory.
This paper demonstrates that the naive limit of -valued gauge theory fails to recover standard Maxwell theory by yielding a flat theory, and instead constructs a corrected sequence of field theories that successfully converge to Maxwell theory by effectively projecting out principal -bundle sectors incompatible with structures, such as those containing magnetic monopoles.
This paper presents a detailed study of the non-resonant production process at the High-Luminosity LHC within the Higgs Effective Field Theory framework, utilizing both cut-based and multivariate analysis methods to derive the first sensitivity projections for several higher-dimensional couplings and demonstrate the channel's potential to probe extended Higgs and top-quark interactions beyond the Standard Model.
This paper demonstrates that within effective field theories of gravity, primordial black holes can survive to the present day by gaining angular momentum through Hawking radiation similarly to general relativity, while their resulting near-extremal states produce detectable tidal forces for future gravitational-wave observatories.
This paper proposes the normalized Wigner negativity rate as a second-moment diagnostic for operator spreading in AdS, demonstrating that at conformal dimension , this rate precisely tracks the growth of Krylov variance and corresponds to the tidal stretch of infalling geodesics via the product of radial position and momentum.
This paper investigates how classical stochastic fluctuations in a background electric field affect a self-interacting charged scalar field theory, utilizing the replica trick to derive an effective current-current interaction and subsequently determining the theory's renormalization group flows across weak and ultra-strong field regimes.
This paper demonstrates that scalar discrete-series unitary irreducible representations of the de Sitter group admit a covariant Gupta-Bleuler structure in the bulk, which induces a corresponding indecomposable boundary realization on conformal infinity linked by a duality-preserving Fourier-type transform.
By computing two-point correlation functions to cubic order in the deformation parameter for the non-Abelian bosonized Thirring model at large , this paper derives the -function and anomalous dimensions to demonstrate the absence of an additional critical point of order , thereby supporting the findings of Destri & de Vega while refuting the claim by Dashen & Frishman.
This paper employs machine learning to demonstrate that while Krylov observables like spread complexity and Wigner negativity can effectively classify symmetry classes and estimate thermofield temperatures, the normalized negativity uniquely captures the informational surplus of chaos by resolving spectral degeneracies and distinguishing second-moment dynamics from fine-grained spectral form factor features.
