Abstract
In this contribution, we report on our study of the properties of the Wilson flow and on the calculation of the topological susceptibility of Sp(Nc) gauge theories for Nc=2 , 4 , 6 , 8 . The Wilson flow is shown to scale according to the quadratic Casimir operator of the gauge group, as was already observed for SU(Nc) , and the commonly used scales t0 and w0 are obtained for a large interval of the inverse coupling for each probed value of Nc . The continuum limit of the topological susceptibility is computed and it is conjectured that it scales with the dimension of the group. Our estimates of the topological susceptibility and the measurements performed in the SU(Nc) Yang-Mills theories by several independent collaborations allow us to test this conjecture and to obtain the universal large-Nc limit of the rescaled topological susceptibility.
