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 establishes the multiplicative renormalizability of CPT-odd Lorentz-violating scalar QCD with adjoint matter at the one-loop level by computing ultraviolet divergences in various Green's functions, demonstrating that all divergences can be absorbed into existing counterterms, and deriving the associated renormalization constants and -functions.
This paper investigates reflection symmetry and Atiyah-Patodi-Singer boundary conditions for twisted Dirac operators on a warped cylinder, establishing that reflection compatibility requires a specific holonomy quantization and demonstrating how spectral flow decomposes into equivariant or mod-two invariants depending on whether the holonomy is fixed or varying.
This paper examines the color structure of two-loop gluon amplitudes in Yang-Mills theory using both color trace and structure constant bases to systematize relations between partial amplitudes.
This paper provides numerical confirmation that large-size Hopf-like solitons exist as local energy minima within the full four-dimensional scalar QED theory, thereby strengthening the Faddeev-Noemi conjecture that these structures arise from a twisted toroidal topology inherent to the model.
This paper investigates how imposing the existence of specific General Relativity solutions, such as Schwarzschild or de Sitter black holes with stealth scalar hair, restricts the parameter space of general quadratic and cubic scalar-tensor theories, revealing that while requiring all such solutions eliminates odd-parity deviations from GR, less restrictive scenarios allow for specific deviations, stability constraints, and modified gravitational wave speeds.
This paper investigates modular flow in a weakly coupled SYK system-bath setup to demonstrate how late-time singularities in correlators reveal the transfer of information across horizons and enable the reconstruction of bulk modular flow in AdS black holes, thereby probing physics beyond the event horizon via quantum extremal surfaces.
This paper investigates Wilson loops on the Coulomb branch of super-Yang-Mills theory by solving for minimal surfaces in AdS, revealing a complete phase diagram for the circular loop's Gross-Ooguri transition and providing evidence that the straight line's expectation value is tree-level exact.
This paper presents a single nonlocal gravity model derived from quantum corrections that successfully interpolates between reproducing cosmological phenomena typically attributed to dark matter and realizing Modified Newtonian Dynamics (MOND) in gravitationally bound systems.
This paper extends thermal field theory to include fermions in rotating equilibrium by developing a comprehensive path-integral framework for both Dirac and Majorana fields, which is then applied to demonstrate that the rapid rotation of neutron stars can significantly enhance neutrino production rates via direct URCA processes.
This paper proposes a unified framework called "Holographic Naturalness" where de Sitter entropy arises from "hairon" fields on orbifold gravitational instantons, simultaneously explaining neutrino masses via a topological information see-saw mechanism and predicting neutrino superfluid condensation as cold dark matter.
