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 demonstrates that tree-level amplitudes for Yang-Mills and Non-Linear Sigma Model theories are completely determined by the principles of locality, unitarity, and newly discovered hidden zeros, as evidenced by the successful reconstruction of their single- and double-soft theorems.
This paper presents new lattice results for sphaleron and non-perturbative thermal axion production rates in QCD across a wide temperature range, utilizing these findings to estimate the thermalization time of ultra-soft gluons during reheating and demonstrating significant deviations from perturbative axion estimates even at the electroweak scale.
This paper proposes using the vanishing of the Roberge-Weiss transition temperature in the chiral limit as a novel probe for the conformal window in many-flavor QCD and presents lattice evidence suggesting that flavors already falls within this conformal regime.
This paper revises the Loop Blow-up Inflation model by demonstrating that generic string loop corrections to the Kähler potential transform the inflationary dynamics from a non-perturbative regime to a power-law plateau, thereby generating updated cosmological predictions that remain consistent with the latest CMB and BAO observational constraints.
This paper initiates the integrability-based study of AdS/CFT dual pairs deformed by Groenewold-Moyal twists by constructing a coupled twisted spin-chain model, deriving its deformed spectrum via the Baxter equation, and successfully matching the leading energy terms with a non-local conserved charge derived from a deformed BMN string solution in the large- limit.
This paper investigates exotic bulk and foliated theta terms in the 2+1d -theory, a fractonic analogue of the compact boson, demonstrating how discontinuous field configurations induce generalized Witten effects where vortex operators acquire momentum charges, including a unique quadrupolar structure in the foliated case.
This paper establishes theoretical and observational constraints on dynamical Chern-Simons gravity by analyzing causality violations in gravitational wave propagation and deriving tighter bounds on its coupling constant through a UV completion involving fermions, ultimately suggesting that dCS corrections to macroscopic gravitational dynamics are likely negligible.
This paper demonstrates that the BEF symplectic form for non-local theories can be derived from an -Lagrangian via the covariant phase space approach, establishing its equivalence to the Barnich--Brandt form for second-order theories and providing a unified framework for understanding corner terms, boundary conditions, and Hamiltonians.
Using the Bethe Ansatz, this paper reveals a novel phase between the Kondo and unscreened phases in the non-Hermitian Kondo model, demonstrating that dissipation drives a phase transition characterized by distinct time scales and a generalized Kondo temperature.
This paper utilizes the Symmetry TFT framework to establish a one-to-one correspondence between higher representations of defect operators and gapped boundary conditions, providing a streamlined method for characterizing defect charges across various dimensions and applications.
