This paper demonstrates that chiral-odd dimeson generalized distribution amplitudes, which encode the spin-orbit correlation in spin-zero mesons, can be experimentally accessed in reactions through the interference between leading one-photon and two-photon exchange amplitudes, offering a direct path to probe this previously unmeasured sector of meson structure at facilities like BES III.
This paper presents a tensor-network formulation for the strong-coupling expansion of QCD with staggered quarks at nonzero chemical potential, deriving analytical results on small lattices and introducing an enhanced method for future large-scale computations.
This paper utilizes the instanton liquid model enhanced by correlated instanton-anti-instanton pairs to derive and analyze the transverse distribution of the color Lorentz force acting on quarks in pions and nucleons, demonstrating that these force form factors are intimately related to gravitational and transversity form factors and yield results for nucleons consistent with recent lattice QCD calculations.
This paper investigates the symmetries and 't Hooft anomalies of 2+1d lattice staggered fermions on sheared tori and Klein bottles, establishing a nontrivial mapping between lattice and continuum symmetries to successfully match their anomalies while developing a general formalism for Hamiltonian lattice models on compact flat spaces.
This paper provides a rigorous proof that generalized Ising models with interaction parameter exhibit "entropic order" at arbitrarily high temperatures and solve NP-hard graph packing problems, leading to the emergence of a novel "entropic glass" phase on arbitrary graphs.
This paper utilizes approximately 4000 lattice QCD propagators on a heavy pion ensemble to analyze relativistic nucleon wavefunctions, revealing that the observed node structure in the spectrum arises from two distinct mechanisms: "superposition nodes" created by combining interpolating fields and novel "built-in nodes" inherent to the s-wave Dirac components of individual fields.
This paper presents a brief biography of William A. Bardeen (1941–2025), an American theoretical physicist at Fermilab renowned for his foundational contributions to the chiral anomaly, quantum chromodynamics, dynamical electroweak symmetry breaking, and heavy-light quark bound states.
This paper introduces a multiscale generative sampler that combines conditional Gaussian mixture models and masked continuous normalizing flows to overcome critical slowing down in lattice field theories, achieving significantly reduced autocorrelation times and enabling unbiased Multilevel Monte Carlo variance reduction for the two-dimensional scalar theory near criticality.
This paper compares the pion decay width in a uniform magnetic field calculated via chiral perturbation theory with lattice QCD results, finding consistency at large magnetic fields while attributing discrepancies at weak fields to differences in pion decay constants.
This paper utilizes QCD sum rule methods to model the resonance as a all-charm tetraquark in a diquark-antidiquark configuration, calculating its mass and decay widths to demonstrate consistency with experimental data and support its interpretation as a tensor state.
This paper presents a variational approach to Initial Boundary Value Problems that treats coordinate maps as dynamical degrees of freedom, ensuring exact conservation of space-time symmetries and Noether charges even in discrete settings, which naturally drives an automatic adaptive mesh refinement process.
This paper presents an extended lattice study of SU(2) gauge theories with one and two adjoint fermion flavors, utilizing multiple methods to demonstrate that both theories reside in the conformal window with chiral symmetry unbroken, yielding continuum-limit anomalous dimensions of approximately 0.170 and 0.291, respectively.
This paper presents a methodology combining open boundary conditions with non-equilibrium Monte Carlo simulations and Stochastic Normalizing Flows to effectively mitigate topological freezing and enable efficient topology sampling in the continuum limit of four-dimensional SU(3) Yang-Mills theory.
This paper presents improved Standard Model predictions for the rare dilepton decays by leveraging recent advances in transition form factor calculations and a robust dispersive evaluation of subleading contributions, yielding precise branching fractions that reveal a mild tension with experimental data for and provide new constraints on physics beyond the Standard Model.
This paper presents a lattice gauge theory formulation that successfully captures the continuum Atiyah-Patodi-Singer index for Dirac operators on domains with compact boundaries by exploiting its equivalence to the spectral flow of generalized domain-wall fermion operators, proving its validity for sufficiently small lattice spacings.
This paper critiques Henry Lamm's manuscript "Ether of Orbifolds" for incorrectly interpreting the quantity as a measure of gauge violation or departure from SU(), clarifying instead that it characterizes the shift in effective lattice spacing and that the associated claims about simulation costs are unfounded.
This paper investigates how fluctuating domain walls in the three-dimensional Ising model modify bulk observables through an effective interaction with the lightest massive mode, identifying a controlled regime governed by a renormalized coupling and validating these universal predictions via Monte Carlo simulations.
This paper demonstrates that lattice Maxwell theory with a -term in a modified Villain formulation exhibits an exact SL(2,Z) duality by employing a non-local transformation within the S-transformation to eliminate non-locality in the absence of monopoles, resulting in a structure for Wilson loops that closely resembles that of non-spin Maxwell theory.
Using modified Villain discretization on both Euclidean lattices and quantum chains, this paper demonstrates that non-invertible topological interfaces arising from flat gauging and T-duality in the two-dimensional compact boson survive discretization by generating non-compact edge modes with infinite quantum dimension, while also showing how these modes can be compactified at rational radii to yield standard defects with finite quantum dimension.
This study utilizes lattice effective field theory to demonstrate that while refined nuclear interactions improve zero-temperature binding and saturation properties, they also significantly lower the critical temperature of symmetric nuclear matter, establishing finite-temperature criticality as a distinct and essential benchmark for future interaction development.
