Description

A search for the decay of the Standard Model Higgs boson into
a bb pair when produced in association with a W or Z boson has been
performed with the ATLAS detector. Data were collected in proton-proton
collisions from Run 2 of the Large Hadron Collider at a centre-of-mass
energy of 13 TeV, final states are considered that contain 0, 1 and 2
charged leptons (electrons or muons), targeting the decays: Z → νν, W →
lν, and Z → ll. In the 1 lepton(WH) channel, the multijet background
contributes a significant fraction of the background events, the
optimization of the selections for multijet rejection has been studied,
and data driven approaches are used to estimate it due to difficulties
encountered to model this background.
