Description
We present a measurement of the signal strength of the Higgs boson decaying to a pair of bottom quarks and produced via Vector Boson Fusion (VBF). The study is performed using 91/fb of pp collision data collected by the CMS experiment at a centre-of-mass energy of 13 TeV. The measurement is performed for events with at least four energetic jets: two b-jets originating from the Higgs boson decay and two forward "VBF-tagged" jets. A Boosted Decision Tree (BDT) classification is used to separate the signal from the major background processes: QCD multijet production and Z+jets events. The signal is extracted from simultaneous fit applied in multiple event categories with varying signal-to-background ratio to the distribution of the invariant mass of two identified b-jets. The VBF signal is observed with a significance of 2.4 standard deviations relative to the background prediction, while the expected significance is 2.7 standard deviations.
