Searches for New Resonances Decaying to Di-Higgs at ATLAS

The latest results of new resonances decaying to Higgs boson pairs from the ATLAS experiment using 13TeV p-p collision datasets are presented. The results include the statistical combination of six di-Higgs decay final states using data collected by ATLAS detector during 2015~2016, and two new analyses that use data collected during full Run2 of the LHC. No significant excess observed. Upper limits on cross section of di-Higgs production via new resonances are reported, with interpretation to several new physics models.
