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 extends the enumeration of planar hypermaps with an alternating boundary to the general case, including Ising-decorated maps, by developing a new strategy involving the simultaneous elimination of two catalytic variables to derive algebraic equations and explicit rational parametrizations, thereby demonstrating that certain properties specific to the previously studied m-constellation case do not hold generally.
This paper proposes that implementing early axion relaxation through high-scale confinement within an $SU(5)$ grand unified theory during inflation generates an early potential that dilutes the axion's energy density, thereby removing the cosmological upper bound on the axion decay constant and allowing it to serve as a viable dark matter candidate for arbitrarily large values across all known axion models.
This paper outlines the key concepts of the Worldvolume Hybrid Monte Carlo method and presents its extension to group manifolds, establishing a rigorous framework for applying this efficient algorithm to lattice gauge theories while avoiding the ergodicity issues of Lefschetz-thimble approaches.
This paper introduces a novel on-shell equivalent reformulation of three-dimensional gravity using divergenceless vector frames inspired by the double copy for Chern-Simons theory, offering a transparent geometric interpretation and connecting the framework to Chern-Simons-like actions, higher-dimensional origins, and extensions.
This paper derives master formulae for tree-level and one-loop scattering amplitudes of arbitrary photon numbers in scalar and spinor QED within non-null background electromagnetic fields using the worldline formalism, thereby extending previous constant-field results to account for realistic laser-plasma dispersive properties through a systematic expansion in the non-null parameter.
This paper extends the classification of gapped phases with categorical symmetries to include anti-unitary time-reversal symmetries by introducing Galois-real fusion categories over as the appropriate mathematical framework, enabling the classification of such phases via module categories and their realization as boundary conditions in a -enriched Symmetry Topological Field Theory.
This paper investigates how spontaneous Lorentz symmetry breaking in metric-affine bumblebee gravity alters rotating black hole shadows, revealing distinct anisotropic deformations like vertical flattening and teardrop shapes that can be distinguished from the standard Kerr metric and potentially observed by the Event Horizon Telescope.
This paper revisits the Friedmann cosmological solution to propose that the Big Bang curvature singularity can be eliminated using a degenerate spacetime metric, while also exploring the emergence of CPT-conjugated worlds and the relevance of an extended version of Einstein's field equations.
This paper proposes a non-perturbative analytical framework for QCD based on a mass gap derived from tadpole/seagull terms, which yields a singular gluon propagator that explains color confinement, linear quark potentials, and scale violations by revealing a more complex dynamical and gauge structure in the QCD ground state than suggested by standard Lagrangian symmetries.
This paper extends the framework of Mysterious Triality by demonstrating that the rational homotopy theory of the toroidification of the 4-sphere admits an action of a maximal parabolic subalgebra of the exceptional Lie algebra , thereby revealing a richer symmetry structure that universally represents the equations of motion for supergravity in M-theory reductions to dimensions.
