  We present a model calculation of T-odd transverse-momentum-dependent
distributions of gluons in the nucleon. The model is based on the assumption
that a nucleon can emit a gluon, and what remains after the emission is treated
as a single spectator particle. This spectator particle is considered to be
on-shell, but its mass is allowed to take a continuous range of values,
described by a spectral function. The final-state interaction that is necessary
to generate T-odd functions is modeled as the exchange of a single gluon
between the spectator and the outgoing parton.
