# Color fields computed in SU(3) lattice QCD for the static tetraquark system

@article{Cardoso2011ColorFC, title={Color fields computed in SU(3) lattice QCD for the static tetraquark system}, author={Nuno Cardoso and M arco Cardoso and Pedro Bicudo}, journal={Physical Review D}, year={2011}, volume={84}, pages={054508} }

The colour fields created by the static tetraquark system are computed in quenched SU(3) lattice QCD, in a 24^3 x 48 lattice at beta=6.2 corresponding to a lattice spacing a=0.07261(85) fm. We find that the tetraquark colour fields are well described by a double-Y, or butterfly, shaped flux tube. The two flux tube junction points are compatible with Fermat points minimizing the total flux tube length. We also compare the diquark-diantiquark central flux tube profile in the tetraquark with the…
