Description
We present a search for Higgs bosons in bh(-->bb) and bbh(-->bb) channels
at a center-of-mass energy of 1.96 TeV using up to 6.3 fb-1 opf data
collected with the D0 detector at the Fermilab Tevatron collider.
In many supersymmetric models the cross-section for the production
of neutral Higgs bosons in association with bottom quarks is greatly
enhanced compared to the standard model and over much of the parameter
space the dominant decayu process is h-->bbar. We search for an excess
of events above the multijet background in events with 3 and 4 b-tagged
jets. Understanding the multijet background in this channel is particularly
challenging. The treatment of the background, the multivariate techniques
used to improved the sensitivity and the limit setting procedure are
discussed.
