摘要：

We analyze field configurations between a static qq̄ in SU(2) lattice gauge theory using a cooling technique, which reduces quantum fluctuations while preserving the string tension and the topological charge. We find clear evidence of chromoelectric flux tube configurations, of transverse size which scales properly and in physical units is of the order of about 0.4 fm. © 1990.
