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.
Using Thermofield Dynamics, this paper demonstrates that a finite-temperature cosmological background modifies the Hawking radiation spectrum of primordial black holes, thereby enhancing their evaporation rate and shortening their lifetimes compared to a zero-temperature vacuum.
This paper demonstrates that the holographic QCD hard-wall model successfully reproduces the constituent counting rule and shows qualitative agreement with experimental data for high-energy fixed-angle scattering, while also providing predictions for other pion scattering processes.
This paper introduces "twisted Feynman integrals" characterized by an additional linear exponential factor in the integrand, establishes their geometric framework as exponential periods, and generalizes standard computational tools to reveal that their Symanzik polynomials become graded and their function space geometry cannot be determined solely by leading singularities.
This paper establishes a direct connection between holographic symmetry algebras in Minkowski space and AdS by demonstrating that the tower of soft gluons generating the asymptotic -algebra in M maps to light ray operators derived from conserved currents in the boundary CFT under a specific conformal transformation.
This paper establishes a unique generating technique for constructing exact bumblebee gravity solutions from vacuum spacetimes by adding a term proportional to the square of the bumblebee field vector (aligned with background geodesics), which is then applied to derive the non-unique bumblebee extension of the Kerr-Newman-Taub-NUT-(anti-)de Sitter spacetime subject to global reality constraints.
This paper introduces a new mechanism called "symmetry spans," where a global symmetry embedded into two larger symmetries enforces infrared gaplessness when no compatible gapped phase exists, offering a powerful tool to establish symmetry-enforced gaplessness even with discrete and non-anomalous continuous symmetries.
This paper demonstrates that a vast class of stationary, axisymmetric black hole solutions in general relativity and Einstein-Maxwell theory can be unified as members of the accelerating Kerr-Newman-NUT family embedded within backgrounds derived from its double Wick rotation, including a newly explored configuration of a Schwarzschild black hole in a generalized rotating and electromagnetic universe.
This paper demonstrates that employing the branch representation in intersection theory significantly simplifies Feynman integral reduction by limiting the required computation to at most variables, thereby overcoming the scalability limitations of traditional methods for multi-loop, multi-leg integrals.
This paper constructs and analyzes two families of quantum soliton geometries in AdS that describe the backreaction of thermal fields via a brane setup in a four-dimensional AdS C-metric, demonstrating how positive-mass solutions replace horizons with smooth origins and establishing a thermodynamic first law within a two-brane framework.
This paper establishes a geometric understanding of the -commutants of free-fermion unitary systems by demonstrating their irreducible transformation under larger or $SU(2k)$ replica symmetries, mapping them to the ground states of effective ferromagnetic Heisenberg models, and revealing a duality where the commutant manifold corresponds to fermionic Gaussian states on sites, thereby providing a compact projection formula for calculating averaged non-linear functionals.
