The chromoelectric and chromomagnetic fields, created by a static gluon-quark-antiquark system, are computed in quenched SU(3) lattice QCD, in a 24{sup 3}x48 lattice at {beta}=6.2 and a=0.07261(85) fm. We compute the hybrid Wilson loop with two spatial geometries, one with a U shape and another with an L shape. The particular cases of the two-gluon glueball and quark-antiquark are also studied, and the Casimir scaling is investigated in a microscopic perspective. This microscopic study of the… Expand
