Search for resonant pair production of Higgs bosons in the b b ¯ b b ¯ final state using pp collisions at s =13 TeV with the ATLAS detector

A search for resonant Higgs boson pair production in the b (b) over barb (b) over bar final state is presented. The analysis uses 126 fb(-1)- 139 fb(-1) of pp collision data at root s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider
