Search for t(t)over-barH production in the all-jet final state in proton-proton collisions root s=13 TeV

A search is presented for the associated production of a Higgs boson with a top quark pair in the all-jet final state. Events containing seven or more jets are selected from a sample of proton-proton collisions at √ s = 13 TeV collected with the CMS detector at the LHC in 2016, corresponding to...
