Description
One of the main results of the Large Hadron Collider Run I was the discovery of the Higgs boson by ATLAS and CMS experiments. The boson has been discovered with a mass of around 125 GeV and all measurements performed so far are compatible with the Standard Model predictions.
However, clear evidence of the boson decaying to a pair of $b$-quarks has not been observed yet, despite it being the dominant decay mode predicted by theory, making this a crucial measurement to establish the nature of the boson.
The ATLAS search for the $b\bar{b}$ decay with the full Run I dataset is presented, considering the Higgs boson production in association with a vector boson ($W$, $Z$).
The analysis is validated with a measurement of $WZ$ and $ZZ$ production, with $Z\rightarrow b\bar{b}$, which is found to be compatible with the Standard Model expectation.
