We perform a two-loop calculation to determine the leading order electroweak corrections to the B-B- mixing amplitude. In this way, we find out the leading order dependence of this amplitude on the mass of the Higgs boson, MH. This dependence is essentially ln2(MH). The interplay between the top quark and the Higgs boson gives rise to the term m4tln2(MH) in the effective Lagrangian. These corrections may lead to a few percent correction to the mixing parameter.
