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 presents a general formula for trigonometric orthosymplectic -matrices associated with any parity sequence by factorizing them into ordered products of -exponents derived from combinatorial Lyndon words, while also verifying their consistency with established affine -matrices and reproducing known results for classical and standard parity cases.
This paper resolves corner ambiguities in the gravitational boundary action at null infinity by constraining it to reproduce tree-level 5-point eikonal amplitudes, thereby naturally deriving the subleading soft graviton theorem and proposing an infinite tower of Goldstone modes via a generalized Geroch tensor to account for higher-order soft insertions and tree-level symmetries.
This paper demonstrates that naturalness scenarios naturally suppress neutrino masses through a mechanism involving numerous mixing partners, leading to a specific tower of additional neutrino mass eigenstates that offers unique, testable signatures in terrestrial oscillation, mass, and neutrinoless double beta decay experiments, thereby extending the model's phenomenological reach beyond cosmology.
This paper constructs new sets of log-canonical coordinates on the character variety of compact Riemann surfaces by combining complexified shear-type and length/twist-type coordinates, which are labeled by families of non-intersecting simple loops and generalize complexified Fenchel-Nielsen coordinates when the loops define a trinion decomposition.
This paper constructs a class of regular black hole geometries by prescribing finite curvature invariants via Ricci and Weyl scalars, demonstrating that the stability of these singularity-free solutions under axial gravitational perturbations critically depends on the shape and peak-to-valley ratio of the resulting effective potential.
This paper presents new exact charged black hole solutions in (2+1)-dimensional gravity using a cubic non-metricity model, revealing novel asymptotically Anti-de Sitter configurations that lack General Relativity counterparts, while analyzing their unique horizon structures, softened singularities, thermodynamic stability, and orbital dynamics.
This paper initiates the study of spherically symmetric spacetimes in second-order effective gravitational theories by proving the existence of regular Vaidya solutions that describe the dynamical formation and evolution of regular black holes without curvature singularities, demonstrating how modified gravity can facilitate energy transfer between matter and gravitational degrees of freedom to resolve singularities.
This paper derives a new class of stable, second-order spin-2 theories featuring a massless spin-2 particle and two massless scalars by enforcing linearized transverse diffeomorphism invariance on a rank-2 tensor field, utilizing a gauge-invariant Lagrangian approach with Bardeen variables to identify the spectrum and propose a non-linear completion via a dynamical metric.
This paper proposes a quantum simulation using an atom coupled to a bimodal optical cavity to emulate a (2+1)D massive gravity model, enabling the observation of spacetime metric fluctuations through the evolution of a fermion's spin with current technology.
This paper proposes a construction of fiducial observers in the near-extremal black hole throat within JT quantum gravity by extending asymptotic time translations via conformal isometries, which enables the calculation of quantum gravitational wormhole contributions to the thermal atmosphere, yielding a finite thermal entropy and a quantum description of the stretched horizon.
