Full Run 2 analysis of Higgs boson decay to b-quarks in CMS — •hessamoddin kaveh — DESY, Hamburg, Germany

After the discovery of the 125 GeV Higgs boson in July 2012, the data collected at the LHC during 2016 and 2017 has lead to the discovery of the Higgs decaying to b-quarks. The focus is now changed to precision measurements in this decay channel. The measurement of the Higgs boson properties in the vector boson associated production mode, with the Higgs boson decaying to a pair of b-quarks using the full pp collision dataset collected by the CMS experiment during Run 2 will be reported. The talk will focus on the statistical and systematic power of the analysis, improving essential analysis methods such as kinematic reconstruction and machine learning approaches, both for the inclusive and simplified template cross-section measurements.
