Description
A basic research goal of high energy physicists is to shed light on the reality of the Higgs mechanism through the study of the Higgs potential. Indeed an important test of the Standard Model is a determination of the form of the Higgs potential and the Higgs field self-coupling. The trilinear self-coupling can be extracted from the measurement of non-resonant Higgs boson pair (HH) production. A measurement of the self-coupling will not be feasible with the data collected during Run 2, but only with the full data set of the HL-LHC. Nevertheless, useful upper limits on the production cross section could be obtained. And, of course, there is always the possibility of a deviation from the Standard Model prediction, which would be an unambiguous sign of new physics at the TeV scale. Recent results for non-resonant HH analyses combination will be presented and interpreted within the SM and BSM theories.
