We are exploring the possible discovery reach for Standard Model
Higgs boson and SUSY Higgs bosons in Run 2 of the Tevatron, using
Monte Carlo models of the signal and background. At the present time,
we are investigating the assoicated production WH and ZH in p-pbar
collisions at sqrt(s)= 2 TeV. We are using PYTHIA Monte Carlo program
to model the signal production from 90 GeV/c**2 to 140 GeV/c**2. We
use COMPHEP for generating Wbb, Zbb (with PYTHIA as the fragmenter of
partons) and PYTHIA to generate other backgrounds such as WW, WZ, ZZ,
W+jets, ttbar and single top backgrounds . The detector simulation is
implemented only by smearing the electromagnetic and hadron energy
measurements as per the observed resolutions in the DØ
detector. Our aim is to employ multivariate techniques for
signal/background discrimination, compare with standard univariate
cuts and combine the WH and ZH channels to extract the minimum
luminosity required for a 5sigma discovery at various Higgs boson
masses. We plan to map the results on to {tan(beta), m_h} plane for
some SUSY model assumptions.
