We numerically investigate the transition of the static quark-antiquark string into a static-light meson-antimeson system. Improving noise reduction techniques, we are able to resolve the signature of string breaking dynamics for n_f=2 lattice QCD at zero temperature. This result can be related to properties of quarkonium systems. We also study short-distance interactions between two static-light mesons.

  1. Open-flavor threshold effects on quarkonium spectrum in the BOEFT

    hep-ph 2026-04 unverdicted novelty 7.0

    BOEFT quantifies threshold-induced shifts in quarkonium masses below threshold by solving coupled Schrödinger equations using lattice potentials and one parameter fixed to the χ_c1(3872) mass.

  2. The Quantum Complexity of String Breaking in the Schwinger Model

    hep-ph 2026-01 unverdicted novelty 6.0

    Quantum complexity measures applied to the Schwinger model reveal nonlocal correlations along the string and show that entanglement and magic give complementary views of string formation and breaking.
