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 proposes that a nearly constant ratio of approximately 2.3 between the peak frequencies of gravitational waves from binary black hole mergers and those from evaporating black holes serves as a robust signature of new black hole physics, potentially allowing for the direct inference of specific properties like the Hayward model's hair parameter.
This paper presents a holographic worldsheet computation of correlation functions involving heavy defect-changing operators (associated with cusps on a 1/2 BPS Wilson line) and light protected operators in super Yang-Mills, deriving and verifying strong-coupling relations for integrated correlators that hold at any coupling.
This paper develops a post-Newtonian framework for binary systems interacting via a scalar field in odd-dimensional de Sitter and anti-de Sitter spacetimes, deriving equations of motion up to 2PN order and demonstrating that the background's conformal algebra manifests as a curvature-dependent deformation of the Poincaré algebra in phase space.
This paper presents the first analytic computation of time-domain gravitational waveform multipoles for hyperbolic black-hole scattering at leading post-Minkowskian order to all orders in velocity, utilizing cut loop integrals and dimensional regularization to derive logarithmic expressions that facilitate the integration of post-Minkowskian fluxes into binary merger waveform models.
This paper investigates thermal two-point functions in AdS by analyzing one-loop Witten diagrams with various interactions, utilizing split representations and the method of images to derive manifestly KMS-periodic spectral and image-sum representations, while also establishing connections between thermal CFT data, effective bulk vertices, and the thermal conformal bootstrap.
This paper presents a systematic method to derive analytical time-domain gravitational waveforms for hyperbolic black-hole scattering at first order in the self-force expansion and all orders in the post-Newtonian/post-Minkowskian expansion by introducing a dimensional-regularization-inspired prescription to resolve divergences and expressing the solution through Lauricella functions.
This paper presents a comprehensive analysis of radion/dilaton portal freeze-in dark matter in stabilized warped extra-dimensional models, demonstrating that keV-TeV scale particles can achieve the observed relic density when the reheating temperature is below the radion mass, while also identifying Lyman-alpha constraints as a unique probe for this scenario.
This paper systematically investigates BPS cohomologies in SYM theory for within the BMN sector, revealing that non-Coulomb graviton cohomologies exist for , that the lightest black hole states are "heavier" brane-fused types with non-trivial R-charge, and that these black hole cohomologies likely possess parity opposite to that of gravitons in the same charge sector.
This paper proposes that Grand Unified Theory models featuring biased domain walls can collapse to form magnetically charged black holes, where the discrete symmetry breaking parameter determines whether these objects are light and short-lived or astrophysical and stable enough to satisfy current observational constraints on magnetic monopole density.
This paper proves a conjectured factorized formula for the determinant of an evaluation matrix associated with a degeneracy graph by establishing a block-triangular structure via graph analogues of Newton polynomials, thereby revealing that the determinant's exponents correspond to overlap volumes of higher-dimensional Young diagrams and enabling the explicit recursive inversion of the matrix.
