Title : "Observation of the Higgs Boson Decaying to Bottom Quarks at CMS"
Speaker Name: Christopher Palmer
Speaker Institution : Princeton University


Abstract : The Higgs boson decay to a bottom quark-antiquark pair has been sought
for decades by the high energy community (i.e. at LEP and Tevatron).
With the observation of the Higgs
boson at LHC during Run 1, the search for this decay channel became
sharply focused. As the bottom quark pair channel is the most
probable decay of the Higgs boson (58%), its observation is both
important in terms of quantifying the Higgs boson and it represents an
important milestone in high energy physics. The results presented use
datasets from the LHC Run 1 and Run 2 (2016+2017) from CMS. This Run
2, 13 TeV dataset corresponds to an integrated luminosity of ~80
fb^-1. The analysis strategy, the background estimation techniques,
and significant analysis improvements from the 2017 data analysis in
CMS are shown. An outlook on the upcoming analysis of the full Run 2
dataset (and beyond) will be discussed.
