Searching for new physics with di-Higgs to 4b final states at ATLAS.
It is not often these days that a completely new channel is developed to search for evidence of new physics at the LHC. When Run-1 of the LHC began, the general consensus was that, compared to final states containing leptons, fully hadronic final states would not be competitive in the search for new physics, because the enormous QCD backgrounds would be overwhelming. In this seminar we will tell the story of how this notion was reversed for Higgs pair production, present the latest Run-1 results of the di-Higgs to 4b searches by ATLAS and CMS, and give the prospects for exploiting this channel in the future, including the potential for dramatically extending the physics reach of the HL-LHC.

Singlet Majorana fermion dark matter: LHC14 and ILC
Exploring a dark matter (DM) candidate using an effective field theory (EFT) framework is a popular approach. However, since the central energy of LHC is going to be 14 TeV and future ILC experiment could also reach 1 TeV, the EFT is not valid any more. In this talk, I will first review our previous work, 1407.1859, then show how we conservatively estimate the power LHC&ILC on EFT by comparing with the UV completed model.
