Description

Motivated by studies of Composite Higgs models based on the $SU(4)/Sp(4)$ coset on the one hand and by large-$N$ limit investigations on the other, we analyse the quenched meson spectrum of Symplectic -- $Sp(2N)$ -- gauge theories on the lattice. We examine fermions in the symmetric representation of $Sp(4)$; we also study fermions in the fundamental, antisymmetric and symmetric representations of $Sp(6)$. The previously computed spectrum of $Sp(4)$ mesons in the fundamental and antisymmetric mesons is also discussed. The $Sp(6)$ spectrum is explored to supplement the work of $Sp(4)$ as well as a step along the way to computing the meson spectrum in the large-$N$ limit of $Sp(2N)$.
