Search for resonant pair production of Higgs bosons in the b b ¯b b ¯ final state using p p collisions at √{s }=13 TeV with the ATLAS detector
Abstract
A search for resonant Higgs boson pair production in the b b ¯b b ¯ final state is presented. The analysis uses 126 fb-1- 139 fb-1 of p p collision data at √{s }=13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond to resonant H H production via gluon-gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV .
