Description

$Sp(2N)$ gauge theories are potentially relevant in the context of Composite Higgs Models and provide an alternative sequence to the more widely studied $SU(N)$ and $SO(N)$ groups in the investigation of the large-N limit of Yang-Mills theories.
In this contribution, we report on our study of the scale setting and of the topological features of the vacuum of $Sp(2N)$ lattice (pure) gauge theories using the Wilson Flow. We measure the topological susceptibility and the value of the scales $t_0$ and $w_0$ for a range of inverse couplings at $N=1,2,3,4$. The continuum and large-N limits of these quantities are discussed and compared to the results obtained in $SU(N)$ lattice gauge theories.
