Abstract: (APS)

A search for resonant Higgs boson pair production in the

b \bar{b} b \bar{b}

final state is presented. The analysis uses

126 {fb}^{- 1} - 139 {fb}^{- 1}

of

p p

collision data at

\sqrt{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

.
