Description

We present a search for non-resonant di-Higgs production in the HH->bbyy decay channel. The measurement uses 139ifb of pp collisions recorded by the ATLAS experiment at a center-of-mass energy of 13 TeV. Selected events are separated into multiple regions, targeting both the SM signal and BSM signals with modified Higgs self-couplings. No excess with respect to background expectations are found and upper limits at 95% confidence level are set on the di-Higgs production cross sections and the Higgs trilinear coupling modifier.
