Abstract
We study the disk-jet connection in supermassive black holes by investigating the properties of their optical and radio emissions utilizing the SDSS-DR7 and the NVSS catalogs. Our sample contains 7017 radio-loud quasars with detection {\it both} at 1.4~GHz and SDSS optical spectrum. We find that the jet powers correlate with the bolometric disk luminosities as $\log P_{\rm jet} = (0.96\pm0.012)\log L_{\rm disk} + (0.79 \pm 0.55)$. This suggests that the jet production efficiency of $\eta_{\rm jet}\simeq1.1_{-0.76}^{+2.6}\times10^{-2}$ assuming the disk radiative efficiency of $0.1$ implying low black hole spin parameters and/or low magnetic flux for radio-loud quasars.
