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 demonstrates that the standard low-energy effective field theory of quantum gravity predicts unobservably small vacuum fluctuations in interferometers, implying that any future detection of large gravitationally-induced length variations would signal a fundamental breakdown of this theory.
This paper proposes an alternative resolution to the black-hole information paradox by suggesting that trans-Planckian effects in string theory cause Hawking radiation to cease around the scrambling time, leaving the black hole predominantly classical with negligible energy loss.
This paper investigates normal mode analysis in relativistic massive transport by demonstrating how particle mass induces coupling between sound and heat channels, alters the branch cut structure responsible for Landau damping, and leads to non-monotonic dependencies in the critical wavenumbers for collective modes.
This paper derives the general non-holomorphic completion for the generating series of BPS indices in Type II Calabi-Yau string compactifications by evaluating the refined Witten index of multi-center supersymmetric quantum mechanics via localization, thereby confirming that the required generalized error functions arise from the spectral asymmetry of scattering states for an arbitrary number of BPS dyons.
This paper classifies positive traces on the Coulomb branch algebras of specific three-dimensional and four-dimensional gauge theories, focusing on quantizations of type Kleinian singularities and algebras associated with pure and gauge theories.
This paper proposes and validates a conjecture that maps bulk loop diagrams in the gravitational Schwinger-Keldysh geometry to loop integrals within a real-time finite-temperature field theory on the black hole exterior, thereby generalizing previous tree-level results and establishing diagrammatic rules consistent with microscopic unitarity and thermality.
This paper reinterprets the circular Unruh effect by demonstrating that the tree-level decay of uniformly rotating particles arises from the emission of negative-energy quanta due to the absence of a global vacuum state, thereby proving that such particles cannot be stable without invoking a thermal bath.
This paper utilizes finite-temperature QCD sum rules with updated quark masses and lattice-informed condensates to predict the thermal evolution of masses and decay constants for , , and mesons up to near-critical temperatures, revealing a suppression hierarchy consistent with binding energies and confirming the -- splitting observed by LHCb.
This paper establishes a connection between Hawking radiation and the double copy by demonstrating that the particle production from a massless scalar scattering off a collapsing electromagnetic background (the single copy of the Vaidya metric) can be equivalently derived through both a diagrammatic exponentiation approach and a semiclassical ray-tracing computation, yielding a thermodynamic distribution consistent with black hole physics.
This paper introduces first-order noncommutative corrections to Einstein-nonlinear electrodynamics using a Drinfel'd twist and Seiberg-Witten map, deriving perturbative solutions for static, spherically symmetric dyonic black holes that account for both intrinsic electromagnetic nonlinearity and noncommutative geometric effects.
