Description
Sp(2N) gauge theories with fermonic matter provide an ideal laboratory to build up phenomenological models for physics beyond the standard model based on novel composite dynamics, where the models include composite Higgs along with partial top compositeness and composite dark matter. Without fermions they also supplement SU(N_c) gauge theories in the large N_c limit. In this talk we report on our recent progress in the numerical studies of Sp(2N) gauge theories discretized on a four-dimensional Euclidean lattice. In particular, we present preliminary results for the low-lying spectra of mesons and chimera baryons in the theories with N=2. We also compute the topological susceptibility for various values of N, which is further extrapolated to the large N limit.
