  We quantify the rate and the signal-to-background ratio for Higgs $\to
b\bar{b}$ detection in double-diffractive events at the Tevatron and the LHC.
The signal is predicted to be very small at the Tevatron, but observable at the
LHC. We exemplify the diagnostic power of hadronic antenna pattern by
considering the topology of hadronic flow corresponding to Higgs $\to b\bar{b}$
events.
