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{sub 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.

Light Hadron Masses from Lattice QCD (2012, background): “A closely related phenomenon occurs in heavy quark physics where string breaking between static quarks can only be observed when one introduces explicitly a “broken string” operator that consists of two separated static-light mesons (Bali et al., 2005; Knechtli and Sommer, 1998).”

The XYZ states: Experimental and theoretical status and perspectives (2019, background): “The phenomenon of the string breaking is sometimes incorporated effectively into potential models through the flattening of the static quark-antiquark potential at relatively large quark-antiquark distances [378–381].”
The equation of state in lattice QCD: with physical quark masses towards the continuum limit (2005, background): “This quantity, strictly speaking, does not exist in dynamical QCD (the string breaks and two mesons are produced [14]).”
