On Nuclearity of $C^{\ast }$-algebras of Fell bundles over \'etale groupoids

In this paper, we show that if E is a Fell bundle over an amenable 'etale locally compact Hausdorff groupoid such that every fiber on the unit space is nuclear, then $C{?}^{\ast }r(E)$ is also nuclear. In order to show this result, we introduce (minimal) tensor products of Fell bundles with fixed $C^{\ast }$-algebras.
