In this paper we investigate, by means of numerical lattice simulations, the topological properties of the trace deformed SU(3) Yang-Mills theory defined on S1×R3. More precisely, we evaluate the topological susceptibility and the b2 coefficient (related to the fourth cumulant of the topological charge distribution) of this theory for different values of the lattice spacing and of the compactification radius. In all the cases we find results in good agreement with the corresponding ones of the standard SU(3) Yang-Mills theory on R4.

Abstract
In this paper we investigate, by means of numerical lattice simulations, the topological properties of the trace deformed SU(3) Yang-Mills theory defined on S1×R3. More precisely, we evaluate the topological susceptibility and the b2 coefficient (related to the fourth cumulant of the topological charge distribution) of this theory for different values of the lattice spacing and of the compactification radius. In all the cases we find results in good agreement with the corresponding ones of the standard SU(3) Yang-Mills theory on R4.File in questo prodotto:
