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 a no-go theorem demonstrating that stationary and axisymmetric Carrollian black holes in dimensions greater than three are necessarily static, while highlighting that rotating solutions can exist in three dimensions via topological re-identification and that accelerating black holes remain possible in four dimensions.
This paper extends the Worldvolume Hybrid Monte Carlo algorithm to systems defined on compact group manifolds by introducing a symplectic structure on the worldvolume's tangent bundle, thereby offering a reliable and computationally efficient framework for addressing the numerical sign problem in lattice gauge theories while resolving ergodicity issues common in Lefschetz thimble approaches.
This paper investigates a scotogenic extension of the Standard Model with two inert doublets and three singlet Majorana fermions, identifying viable parameter spaces for radiative neutrino mass generation and dark matter while revealing that approximately 60% of these regions are excluded by recent CMS measurements of the boson mass due to constraints on the oblique parameter .
This paper investigates the holographic implications of -charged warped BTZ backgrounds by deriving their non-linear asymptotic symmetries, which form a Poisson algebra that linearizes to two commuting copies of the Virasoro Kac-Moody algebra, thereby confirming a match with the symmetry structure of symmetric product orbifolds of -deformed CFTs.
This paper extends BCFW-like recursion relations to deformed associahedra and D-type cluster polytopes, demonstrating how these geometric triangulations capture tree-level and one-loop scattering amplitudes in multi-scalar cubic theories and offering a pathway to recover effective field theory amplitudes.
This paper proposes an observer-dependent geometric definition of conical deficits in spacetimes with NUT parameters, demonstrating that the perceived conicity along the symmetry axis varies with the choice of timelike Killing vector and challenging the standard interpretation of conicity differences as indicators of acceleration-induced strings or rods.
This paper demonstrates that tropicalizing scalar quantum field theory yields an exact, non-linear recursion solution for the quantum effective action that enables a polynomial-time algorithm to sample moduli spaces of metric graphs, thereby proving that perturbative QFT computations lie in the polynomial-time complexity class and successfully evaluating the beta function at 50 loops.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper extends U-dualities in maximally supersymmetric non-chiral supergravity to fermionic degrees of freedom via Spin- and Pin-lifts, utilizing the Swampland Cobordism Conjecture to predict new codimension-two reflection branes that act as charge conjugation symmetries and support specific BPS objects, braiding rules, and bound states.
This paper investigates how detector-based measurements in a CFT induce Lüders state updates, determining their associated boundary space-time regions and corresponding modifications to the bulk gravity state and semiclassical parameters within the AdS/CFT framework.
