For both Υ(9.5,b̄b) and T(t̄t), the decay into Higgs scalar plus photon is calculated, employing a triangle-diagram estimate for the dependence of this decay matrix element on the Higgs-scalar mass. This mass dependence gives a significant supression, but the decay should still be readily observable, if energetically allowed.
