Query: The Double Copy of Massive Scalar-QCD   We construct the gravitational theory emerging from the double-copy of
massive scalar quantum chromodynamics in general dimensions. The resulting
two-form-dilaton-gravity theory couples to flavored massive scalars
gravitationally and via the dilaton. It displays scalar self-interaction terms
of arbitrary even order in the fields but quadratic in derivatives. We work out
the emerging Lagrangian explicitly up to the sixth order in scalar fields and
propose an all order form.
