Observation of the Higgs decay to beauty quarks

Higgs bosons decaying to b-quark pairs were searched in the production modes associated with vector bosons using 79.8 fb$^{-1}$ data of pp collisions at the center of mass energy of 13 TeV provided by the Large Hadron Collider (LHC) and recorded by the ATLAS detector. The observed (expected) signifi...

Sumario:Higgs bosons decaying to b-quark pairs were searched in the production modes associated with vector bosons using 79.8 fb$^{-1}$ data of pp collisions at the center of mass energy of 13 TeV provided by the Large Hadron Collider (LHC) and recorded by the ATLAS detector. The observed (expected) significance of the signal is 4.9 (4.3) $\sigma$. This result was combined with the $H\rightarrow b\bar{b}$ results of Run 1 and Run 2 datasets for vector boson fusion production and associated production with top quark pairs. A combination with $H\rightarrow \gamma\gamma$ and $4\ell$ decay modes in associated production with vector bosons was performed using the Run 2 results. The observed (expected) significance of this production modes is 5.3 (4.8) $\sigma$.
