Sumario:The $VH(H\rightarrow bb)$ analysis that led to the observation of the Higgs boson decaying into pairs of bottom quarks has been extended with further interpretation of the signal measurement. The cross sections for the $VH$ production times the $H\rightarrow bb$ branching ratio have been measured in exclusive regions of phase space. These measurements have been used to search for deviations from the Standard Model predictions with an Effective Field Theory (EFT) approach. An overview of the $VH(H\rightarrow bb)$ 2018 analysis with the ATLAS detector and the EFT interpretation are presented.
