A note on the twisted degree 6-L-function for Hermitian cusp forms of degree 2

Let [Formula: see text] be a cuspidal Hermitian eigenform of degree two over [Formula: see text], with first Fourier–Jacobi coefficient not identically zero. Building on a paper by Das and Jha, we prove the meromorphic continuation to [Formula: see text] and the functional equation of a degree six [Formula: see text]-function attached to [Formula: see text] by Gritsenko, twisted by a Dirichlet character.
