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 in spin-1 fermionic systems, Lorentz symmetry breaking introduces a non-topological, momentum-dependent non-Abelian background potential that modifies the conventional chiral anomaly equation, resulting in a non-quantized anomaly coefficient.
This paper employs perturbative methods within de Sitter electroweak theory to calculate the production rates and resulting number density of bosons emitted from neutrino decays in the early Universe, analyzing their dependence on particle momenta and renormalization mass.
By combining advanced quantum Monte Carlo simulations with a novel loop estimator for Rényi entanglement entropy, this study demonstrates that an SU() generalization of the Heisenberg antiferromagnet in 1+1 dimensions exhibits weak first-order pseudocriticality driven by proximity to a complex conformal field theory, a finding that accurately recovers the real part of the complex central charge for and reinterprets the dimerized phase of the spin-1 chain as pseudocritical.
This paper demonstrates that the excitation energy of long strings on deformed BTZ black hole backgrounds formed near NS5 branes corresponds to the spectrum of deformed , with winding modes mapping to twisted sectors of a symmetric product theory.
This paper presents a general Bayesian algorithm for inferring the gravitational constant from wide binary orbits using 3D modeling and applies it in a pilot study of 32 Gaia systems with HARPS radial velocities, finding tentative evidence for a deviation from Newtonian gravity that is heavily influenced by a single outlier system and requires further verification.
This paper demonstrates that gravitational instantons, specifically Eguchi-Hanson geometries, induce quantized fluxes that enforce global boundary conditions on fermion wavefunctions and, upon summation over flux sectors in the path integral, gauge the Standard Model's 1-form symmetry, thereby proving it cannot persist as an exact global symmetry while simultaneously inducing exponentially suppressed baryon- and lepton-number violating processes.
This paper introduces a novel technique using supersymmetric localization and the Fermi gas formalism to derive exact expressions for supersymmetric Wilson loops in ABJM theory for arbitrary and , successfully reproducing known expansions and resolving a longstanding discrepancy between numerical data and semiclassical predictions for the BPS Wilson loop.
This paper presents a unified theoretical framework demonstrating how Wilson loops serve as a fundamental link between nonperturbative gauge dynamics, topological band theory, and interacting electron systems, revealing that both quantized Hall conductivity and quasiparticle statistics originate from the same topological invariant: the linking number of Wilson loops.
This paper computes the Hilbert series of various three-dimensional quiver gauge theories by taking a specific limit of the superconformal index using auxiliary fugacities to isolate moduli space branches, thereby validating known results for linear, circular, star-shaped, and orthosymplectic quivers while offering new predictions for affine Dynkin cases.
This paper investigates operator growth in Brownian spin SYK models by deriving a closed master equation for the full operator-size distribution, enabling exact leading-order solutions and a systematic expansion that reveals the crucial role of higher-order corrections in quantum scrambling and chaos.
