Title:  "Search for Standard  Model  Higgs in the ZH --> l^+ l^- bb Channel at
          CDF II."
Asbtract:
     We search for the Higgs Boson in 1 fb^-1 from the process ZH-> l^+
     l^- bb in both ee and mm channels. These channels have a small
     background of mostly real Z + jets events due to the requirement of
     two leptons and a Z mass constraint. We correct the two candidate
     Higgs jets with an artificial neural network which assigns missing
     transverse energy (MET) to the jets according to their MET
     projections and relative f. To maintain signal efficiency and
     improve signal discrimination, we employ an additional neural
     network trained to discriminate event kinematics of ZH compared to
     the main Z + jets background and the kinematically different tt
     background. We set an upper limit on s(ZH)*BR(H->bb) from 100-150
     GeV/c^2 .  At 115 GeV/c ^2 ,  we set a limit of 1.3 pb, which is 16
     times the SM expectation.
