We calculate the meson spectrum of the Sp(4) lattice gauge theory coupled to\ntwo fundamental flavours of dynamical Dirac fermions. We focus on some of the\nlightest (flavoured) spin-0 and spin-1 states. This theory provides an\nultraviolet completion for composite Higgs models based upon the SU(4)/Sp(4)\ncoset. We analyse the strongly coupled dynamics in isolation, without explicit\ncoupling to the standard model. We carry out continuum extrapolations using\ndynamical ensembles generated at five different values of bare lattice\ncoupling, and for several values of the bare fermion mass. We fit the resulting\nmeson masses and decay constants to a low-energy effective field theory built\nalong the ideas of hidden local symmetry. We also compare our results to those\nof other closely related lattice gauge theories, which have matter content\nconsisting of two fundamental Dirac flavours.\n
