Abstract
We have studied the potential of the CDF and DO experiments to discover a l ow-mass standard model Higgs boson, during run II, via the processes p (p) over bar --> WH --> lvb (b) over bar, p (p) over bar --> ZH --> l(+)l(-)b ( b) over bar and p (p) over bar --> ZH --> v (v) over bar b (b) over bar. We show that a multivariate analysis using neural networks that exploits all the information contained within a set of event variables leads to a signif icant reduction, with respect to any equivalent conventional analysis, in t he integrated luminosity required to find a standard model Higgs boson in t he mass range 90 GeV/c(2) < M-H < 130 GeV/c(2). The luminosity reduction is sufficient to bring the discovery of the Higgs boson within reach of the F ermilab Tevatron experiments, given the anticipated integrated luminosities of run II, whose scope has recently been expanded.
