Constraints on anomalous couplings of the Higgs boson from pair production searches

The study of the anomalous non-resonant HH production is presented from the point of view of effective field theory (EFT) parameterization. The searches for pp → HH → γγWW , pp → HH → γγbb and pp → HH → bbbb processes by ATLAS experiment at the Large Hadron Collider (LHC) are reproduced. The selecti...

Summary:The study of the anomalous non-resonant HH production is presented from the point of view of effective field theory (EFT) parameterization. The searches for pp → HH → γγWW , pp → HH → γγbb and pp → HH → bbbb processes by ATLAS experiment at the Large Hadron Collider (LHC) are reproduced. The selection efficiencies and exclusion limits on the HH production cross for different Beyond Standard Model (BSM) EFT benchmark models are obtained using the fast Monte-Carlo simulation of the ATLAS detector.
