Six years since the discovery of the Higgs boson and the analysis of over
100fb-1 of data have been necessary for the ATLAS experiment to observe the
most abundant Higgs decay channel into b-quark pairs.
The seminar will explain the challenges of this observation, and present in
details the most sensitive search channel, where the Higgs is produced in
association with W or Z bosons. The longer-term perspectives for studies of
this part of the Higgs sector will also be discussed.
