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 investigates the gravimagnetic dipole spacetime formed by two counter-rotating black holes in equilibrium via a tensionless Misner string, deriving the velocities of circular rotation trajectories for both massive and massless particles along their geodesics.
This paper demonstrates that solitonic boson stars with positive binding energy can remain dynamically stable against nonlinear radial perturbations, thereby challenging the conventional view that negative binding energy is a necessary condition for the stability of such compact objects.
This paper develops a vector bundle supermanifold framework with Fermi normal coordinates to geometrically interpret scalar-fermion effective field theories, specifically applying this formalism to the Standard Model Higgs sector to analyze the phenomenological consequences of custodial symmetry violation and field space non-analyticities.
This paper establishes a no-go theorem demonstrating that the most general bumblebee vector-tensor cosmology cannot simultaneously maintain a homogeneous and isotropic background, avoid extra propagating degrees of freedom, and ensure healthy linear perturbations, as enforcing the correct number of modes inevitably leads to infinite strong coupling.
This paper presents a parametric study of charged black holes in Weyl conformal gravity, deriving analytic expressions for horizons and photon spheres to reveal exotic spacetime structures—such as nested black holes with trapped Cauchy horizons and triple-horizon collisions—that arise due to the absence of the inverse quadratic term and differ fundamentally from standard general relativity.
This paper challenges the notion that extremal black holes are inherently unstable amplifiers of new physics by demonstrating that perturbed extremal Reissner--Nordström AdS black holes can possess regular, non-spherical horizons where scalar stress-energy divergences do not prevent finite backreaction and smooth geodesic crossing.
These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.
This paper reassesses the feasibility of using coherent state variational methods for large gauge theories by introducing a new implementation applicable to SU() lattice gauge theories with or without fermions, and presents initial results for Hamiltonian Yang-Mills theory on an infinite two-dimensional spatial lattice.
This paper presents a method for systematically constructing canonical differential equations to compute Feynman integrals associated with complex geometries like elliptic curves and Calabi-Yau varieties, using the two-loop sunrise integral as a primary example to demonstrate the approach beyond multiple polylogarithms.
This paper reconstructs the historical development of Fermi's statistics, tracing how Enrico Fermi's early interest in entropy and the limitations of Sommerfeld's quantization led him to apply the Exclusion Principle to non-interacting particles, thereby establishing the statistical framework for an ideal monatomic gas.
