    Let \(\pi\) be the automorphic representation of \(\textrm{GSp}_4(\mathbb{A})\) generated by a full level cuspidal Siegel eigenform that is not a Saito-Kurokawa lift, and \(\tau\) be an arbitrary cuspidal, automorphic representation of \(\textrm{GL}_2(\mathbb{A})\). Using Furusawa's integral representation for \(\textrm{GSp}_4\times\textrm{GL}_2\) combined with a pullback formula involving the unitary group \(\textrm{GU}(3,3)\), the authors prove that the \(L\)-functions \(L(s,\pi\times\tau)\) are “nice”.

    The converse theorem of Cogdell and Piatetski-Shapiro then implies that such representations \(\pi\) have a functorial lifting to a cuspidal representation of \(\textrm{GL}_4(\mathbb{A})\). Combined with the exterior-square lifting of Kim, this also leads to a functorial lifting of \(\pi\) to a cuspidal representation of \(\textrm{GL}_5(\mathbb{A})\).

    As an application, the authors obtain analytic properties of various \(L\)-functions related to full level Siegel cusp forms. They also obtain special value results for \(\textrm{GSp}_4\times\textrm{GL}_1\) and \(\textrm{GSp}_4\times\textrm{GL}_2\).
