Flux-tube structure and beta-functions in SU(2)
P. Pennanen, A. M. Green, C. Michael
Abstract
The spatial distribution of the action and energy in the colour fields of flux-tubes is studied in lattice SU(2) field theory for static quarks at separations up to 1 fm at beta=2.4, 2.5. The ground and excited states of the colour fields are considered. Sum rules are used to get estimates of generalised beta-functions.
