Description

The most dominant but experimentally difficult decay channel of the HIggs boson, into a pair of bottom quarks
has already been established using the Higgs boson production associated with a vector boson (VH, V = W or Z),
when V decays leptonically. The relatively more abundant and the second largest Higgs boson production mode,
the vector boson fusion (VBF) process, is suitable to study this decay mode more precisely. Though marked by a
all hadronic final states the topology of the VBF events provides a good handle to tackle the QCD multi-jet background
significantly. Dedicated VBF topological event triggers and rigorous use of machine learning (ML) make the result
sensitive. The recent measurement by the CMS collaboration using Run-2 data of the LHC will be presented in
this talk.
