The rare decay H → γγ is a promising detection channel for an intermediate mass Higgs boson. We compute its two-loop O(αGFm 2 t ) correction in the standard model and find that it is much smaller than the corresponding QCD correction. The analogous correction to the amplitude for gg → H is recovered as a special case. The generalization of our result to other models is also briefly indicated.

A charge q moving in a reference laboratory system with constant velocity V in the X-axis produces in the Z-axis a longitudinal, phase free, vacuum magnetic field which is identified as the radiated B (3) field of Evans, Vigier and others.

A short outline is given on the application of differential regularization to QCD in the background-field method. The derivation of the propagators in the background gluon field as short-distance expansions is described and the renormalization of the theory is mentioned.
