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 offers an introduction to the cosmological multiverse for artists, explaining how general relativity and the cosmological constant lead to the multiverse hypothesis as a solution to a major puzzle, while also highlighting the unresolved "measure problem" regarding predictions in eternally accelerating universes.
This paper investigates the structure of abelian higher-spin cubic interactions and their corresponding supercurrents, demonstrating that these vertices are fully determined by specific analytic supercurrents derived from the principal supercurrent and exploring their component content and associated gauge transformations.
This paper establishes a correspondence between thermal, flat-space, and defect conformal partial waves using the shadow formalism, demonstrating how thermal blocks can be systematically derived from their flat-space and defect counterparts to obtain the thermal Casimir equation and relate defect two-point blocks to thermal one-point blocks.
This paper clarifies that observational evidence for effective phantom dark energy, derived from background-level reconstructions within standard cosmological assumptions, does not necessarily imply the existence of fundamental phantom fields, microscopic instabilities, or a catastrophic cosmic future, but rather can arise from various physical mechanisms without violating fundamental energy conditions.
This paper presents a new method for directly separating the linearized Einstein equations in a Kerr black hole background, aiming to bypass the limitations of the conventional approach that relies on solving Teukolsky equations followed by metric reconstruction.
This paper proposes a proof of the Riemann Hypothesis by constructing a one-dimensional quasicrystal from the logarithms of prime numbers, demonstrating that the Fourier self-duality of its scattering amplitude forces the real parts of all non-trivial Riemann zeta zeros to equal 1/2.
This paper employs on-shell and unitarity-based methods to derive renormalization group equations for the most general axion-like particle effective field theory, demonstrating that these techniques offer a more efficient and elegant alternative to standard Feynman diagram calculations while explicitly verifying connections between CP-dual operator anomalous dimensions.
This paper establishes an equivalence between SYM theories on orbifolds and gauge theories on smooth manifolds with Gukov-Witten and twist defects, utilizing this framework to compute partition functions on spaces with conical singularities by interpreting the defects as inducing multivalued fields analogous to branched covers.
This paper derives new bounds on Wilson coefficients in gravitational effective field theories by employing fully crossing symmetric dispersion relations that isolate low-energy couplings without relying on the forward limit, successfully validating the method against known scalar and graviton scattering results while establishing novel constraints on graviton interactions with massive spin-4 states.
This paper demonstrates through rigorous quantum statistical analysis of free fermions that the commonly assumed local differential thermodynamic relations in relativistic spin hydrodynamics fail even at global equilibrium, revealing unavoidable corrections to the spin density-pressure relationship that cannot be resolved by entropy-gauge transformations.
