Description
I will present the search for boosted Higgs boson with transverse momentum greater than 450 GeV decaying into bottom quark pairs using LHC full run 2 dataset collected by the CMS experiment.
In this search, we employed the latest jet substructure variables and b-tagging techniques based on a deep neural network to reduce the overwhelming QCD backgrounds.
An excess of events above background is observed with a local significance of 2.5 standard deviation, while the expectation is 0.7.
The measured Higgs production cross sections is also presented as a function of transverse momentum of the Higgs boson and compared with the latest gluon-gluon fusion prediction with finite top-mass corrections.
