Description

H ->bb 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 Energy Transfer and leptons coming from the decay of a weak vector boson produced together with the Higgs.

In this talk, the latest search for H->bb decays associated with a W or Z boson with the ATLAS detector will be presented. Furthermore, the first VH->bb 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 in the form of Effective Field Theory models.
