Sp(2N) gauge theories with fermonic matter provide an ideal laboratory to build extensions of the standard model based on novel composite dynamics. Examples include composite Higgs along with top partial compositeness and composite dark matter. Without fermions, their study also complements those based on SU(Nc) gauge theories with which they share a common sector in the large Nc = 2N limit. We report on our recent progress in the numerical studies of Sp(2N) gauge theories discretised on a four-dimensional Euclidean lattice. In particular, we present preliminary results for the low-lying mass spectra of mesons and chimera baryons in the theories with N = 2. We also compute the topological susceptibility for various values of N, extrapolate the results to the large N limit, and discuss certain universal properties in Yang-Mills theories.
