Query: Has the anomalous single production of the fourth SM family quarks
  decaying into light Higgs boson been observed by CDF?   Superjet events observed by the CDF Collaboration are interpreted as
anomalous single production of the fourth SM family u_4 quark, decaying into a
new light scalar particle. The specific predictions of the proposed mechanism
are discussed.
