Using lattice QCD to study coupled-channel scattering, the authors find that interactions are weak near threshold and show no evidence of bound states or resonances between the state and the threshold.

Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.
Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.

Using the QCD sum rule method, this paper investigates the properties of two heavy-quark hadronic molecules, and , predicting their masses and relatively broad decay widths to demonstrate their instability against dissociation.
Simplicity of confinement in SU(3) Yang-Mills theory
The paper introduces a new topological observable called "simplicity," based on the Betti numbers of Abelian monopole current loops in SU(3) Yang-Mills theory, which provides a more accurate determination of the deconfinement temperature and serves as a potential new order parameter for studying the phase structure of QCD.
Numerical Evaluation of a Soliton Pair with Long Range Interaction
This paper numerically evaluates the interaction energy between finite-sized topological solitons (monopoles) to demonstrate how their physical dimensions cause deviations from the standard Coulomb potential at short distances, drawing a comparison to the running coupling constant in perturbative QED.
Investigation of the ensemble of maximal center gauge
To address the problem of underestimating string tension in center vortex detection, this paper proposes replacing unrestricted maximization in Maximal Center Gauge with a maximization restricted to the Gaussian-distributed part of the local gauge maxima ensemble.
The axial-vector form factor of the nucleon in a finite box
This paper investigates the finite-volume effects on the nucleon's axial-vector form factor using chiral Lagrangian at the one-loop level, demonstrating that implicit mass shifts dominate the results and introducing a generalized reduction scheme for evaluating finite-box loop integrals.
Flowing Through Hilbert Space: Quantum-Enhanced Generative Models for Lattice Field Theory
This paper proposes a hybrid quantum-classical normalizing flow model that integrates parameterized quantum circuits into a generative architecture to enhance sampling efficiency and expressivity for high-dimensional distributions, using lattice field theory as a primary benchmark.
Goldstone bosons across thermal phase transitions
This paper investigates how the Goldstone mode in a complex scalar field theory evolves across a thermal phase transition, demonstrating that the transition can be characterized by a shift from weak to strong thermal damping of the mode.
Three-qubit encoding in ytterbium-171 atoms for simulating 1+1D QCD
This paper proposes a resource-efficient method for simulating 1+1D quantum chromodynamics by encoding three qubits—representing quark color—within the electronic, nuclear, and motional states of individual ytterbium-171 atoms.
Lattice QCD Determination of the Collins-Soper Kernel in the Continuum and Physical Mass Limits
This paper presents a first-principles lattice QCD determination of the Collins-Soper kernel at the continuum and physical mass limits, providing a precise nonperturbative constraint on its long-distance behavior that bridges lattice calculations with phenomenological TMD studies.
