  We present compact analytic formulae for all one-loop amplitudes representing
the production of a Higgs boson in association with two jets, mediated by a
colour triplet scalar particle. Many of the integral coefficients present for
scalar mediators are identical to the case when a massive fermion circulates in
the loop, reflecting a close relationship between the two theories. The
calculation is used to study Higgs boson production in association with two
jets in a simplified supersymmetry (SUSY) scenario in which the dominant
additional contributions arise from loops of top squarks. The results presented
here facilitate an indirect search for top squarks in this channel, by a
precision measurement of the corresponding cross-section. However, we find that
the potential for improved discrimination between the SM and SUSY cases
suggested by the pattern of results in the 1- and 2-jet samples is unlikely to
be realized due to the loss in statistical power compared to an inclusive
analysis.
