The Width of the Colour Flux Tube
arXiv:hep-lat/9411060 · doi:10.1016/0920-5632(95)00207-P
Abstract
We discuss and rederive in a general way the logarithmic growth of the mean squared width of the colour flux tube as a function of the interquark separation. Recent data on 3D $Z_2$ gauge theory, combined with high precision data on the interface physics of the 3D Ising model fit nicely this behaviour over a range of more than two orders of magnitude.
