We present the first results on scalar glueballs in cold, dense matter usinglattice simulations of two color QCD. The simulations are carried out on a $6^3\times 12$ lattice and use a standard hybrid molecular dynamics algorithm forstaggered fermions for two values of quark mass. The glueball correlators areevaluated via a multi-step smearing procedure. The amplitude of the glueballcorrelator peaks in correspondence with the zero temperature chiral transition,$\mu_c = m_\pi/2$, and the propagators change in a significant way in thesuperfluid phase, while the Polyakov loop is mearly insensitive to thetransition. Standard analysis suggest that lowest mass in the $0^{++}$ gluonicchannel decreases in the superfluid phase, but these observations need to beconfirmed on larger and more elongated lattices These results indicate that anonzero density induces nontrivial modifications of the gluonic medium.
