Archimedean theta-packet conjecture

Let FF be a real or complex local field, let GG be an even orthogonal or unitary group over FF, and let ψ\psi be a local AA-parameter with bounded image on the Weil group. Let Πψθ(G)\Pi_\psi^\theta(G) be the theta-packet constructed from local theta correspondence, together with its component-group parametrization. Archimedean theta-packet conjecture. The properties listed for Πψθ(G)\Pi_\psi^\theta(G) over non-Archimedean fields in the theorem preceding this conjecture also hold when FF is real or complex. These properties concern independence from the auxiliary dual-pair choices and auxiliary data, multiplicity-freeness, agreement with Moeglin's packet where defined, containment of the associated LL-packet, and satisfaction of LIR-B. The conjecture extends the established non-Archimedean description of theta-packets to Archimedean local fields; the source does not state that it has been proved.
