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 proposes an economical five-dimensional $SU(5)$ brane-world model where a single adjoint scalar field and a singlet dynamically realize domain walls that simultaneously localize fermions, gauge fields, and the Higgs field, while providing a geometric solution to the doublet-triplet splitting problem and reproducing Standard Model Yukawa couplings.
Using the one-boson-exchange model and the Gaussian expansion method, this study investigates the interaction and finds that several -- wave mixed molecular states can form in specific isospin and angular momentum channels, potentially providing a theoretical interpretation for the and resonances.
The paper proves that in heterotic orbifolds, the leading-order tree-level Yukawa couplings possess an exact "column texture" where all left-handed generations share a universal coefficient, implying that the observed complexity of fermion masses and mixing must arise from higher-order string corrections rather than the primary amplitude.
The paper proves that in ghost-free dRGT massive gravity with two mass terms, the helicity-2 gravitational modes always propagate on the metric lightcone in the high-frequency limit, regardless of the background spacetime.
The paper develops a mathematical framework for two-flavor neutrino oscillations under non-Hermitian dynamics, concluding that the density matrix prescription by Brody and Graefe is superior to the bi-orthonormal metric approach because it preserves probability and reveals non-Markovian behavior in the steady state.
This paper demonstrates that the decoupling of curvature perturbations in the Kerr metric (such as the Teukolsky equations) is a direct consequence of a hidden Kähler geometry, where the self-dual nature of the background allows differential operators to preserve component decompositions without mixing them.
This paper demonstrates that static, spherical black holes with resonant hair are dynamically unstable and undergo spontaneous symmetry breaking, ultimately splitting into a bosonic lump and a bald black hole or imploding into one through non-spherical processes.
This paper develops a quantization method for general reducible gauge theories with broken gauge symmetry by using a Stueckelberg-type procedure to restore gauge invariance, allowing for the derivation of partition functions and one-loop effective actions via the covariant Schwinger-DeWitt technique, specifically applied to massive antisymmetric tensor fields in $AdS$ space.
This paper demonstrates how to take the flat space limit of the ABJM theory by implementing a Carrollian limit for fermions, ultimately showing that the resulting theory possesses an infinite-dimensional Carrollian superconformal symmetry that could serve as a dual to M-theory in flat space.
This paper generalizes the connected wedge theorem by using a new framework of generalized entanglement wedges to establish bounds on mutual information and relate bulk scattering configurations to the connectivity of entanglement wedges in both AdS and asymptotically flat spacetimes.
