Abstract: We report on the status of our programme to simulate Sp(2N) gauge theories on the lattice. Motivatedby the potential realization of an SU(4)/Sp(4)SO(6)/SO(5) composite Higgs model andthe applications to self interacting dark matter, we first perform dynamical simulations of Sp(4)theories with two Dirac flavors in the fundamental representation. Preliminary results of the mesonspectrum are presented, along with discussion of the lattice systematics. We also introducetwo-index anti-symmetric Dirac fermions. Such fermions are relevant in the context of partial topcompositeness, provided they carry SU(3) color quantum numbers, and hence we introduce three(Dirac) copies of them. We present the quenched meson spectrum and explore the phase spaceof bare lattice parameters. For all the numerical simulations we use the standard Wilson latticegauge and fermion actions.
