Measurements of the Higgs boson decays to two bottom quarks

$H \rightarrow b\bar{b}$ decays allow to probe the Yukawa coupling of the Higgs boson to down type quarks. Observing these processes at the LHC is extremely challenging due to the large multi-jet background; however, this can be greatly suppressed by triggering on Missing Transverse Energy and charg...

description $H \rightarrow b\bar{b}$ decays allow to probe the Yukawa coupling of the Higgs boson to down type quarks. Observing these processes at the LHC is extremely challenging due to the large multi-jet background; however, this can be greatly suppressed by triggering on Missing Transverse Energy and charged leptons coming from the decay of a weak vector boson produced together with the Higgs boson. In this paper, the latest measurement for $H \rightarrow b\bar{b}$ decays associated with a $W$ or $Z$ boson with the ATLAS detector will be presented. Furthermore, the first $VH, H \rightarrow b\bar{b}$ differential measurement in bins of transverse momentum of the vector bosons will be discussed; this type of differential measurement is particularly sensitive to Beyond Standard Model physics, as probed through an Effective Field Theory approach.
