The measurement of Higgs pair production will be a cornerstone of the LHC program in the coming years. Double Higgs production provides a crucial window upon the mechanism of electroweak symmetry breaking and has a unique sensitivity to the Higgs trilinear coupling.

The Drell-Yan (DY) process stands for a unique probe to testing initial-state effects that is not accompanied with any final state interaction, either energy loss or absorption.

The lack of conclusive evidence for new physics in Run I of the LHC suggests that future discoveries may manifest themselves with small numbers of signal events.
