摘要
Instantons in the stochastic confining background are influenced by both the one-loop renormalisation in the background and a direct interaction with the background. Stochasticity (finite correlation length) of the background drastically changes the ir properties and yields a convergent instanton density even neglecting interinstanton interaction, while the packing parameter (p/R)(4) decreases due to the background.
