Search for associated production of a Z and a Higgs Boson in $\ell\ell b\bar{b}$ final states at D0

A search for the standard model Higgs boson was performed in the channel $ZH\rightarrow\ell\ell b\bar{b}$ with the D0 detector at the Fermilab Tevatron collider with 4.2~fb$^{-1}$ of data. Events are selected with at least two reconstructed jets and a Z candidate reconstructed from the two leptons. A random forest of decision trees was trained to distinguish between signal and background events in two orthogonal $b$-tag samples. This channel is powerful in the search for a low mass Higgs.
