Interference Effects in Di-Higgs-Production in the singlet extension of the Standard Model — •Finn Feuerstake1, Elina Fuchs1,2, and Tania Robens3 — 1Leibniz Universität Hannover — 2Physikalisch-Technische Bundesanstalt Braunschweig — 3Institut Ruder Bošković Bijenička Zagreb
Real singlet models are simple extensions of the SM as these models add a new Higgs-like scalar that transforms as a singlet under the SM gauge group. For the case of an additional particle that is heavier than twice the SM-Higgs this scalar, labelled S, could play a role in resonant-enhanced pp→ hh production. We here simulate samples for such scenarios for the inclusive process, the scenario where pp→ S→ hh only, as well as production without the intermediate resonance. By comparing distributions of these three processes in different observables, such as the invariant mass or the final state transverse momenta, taking the finite width of the heavy scalar into account, we discuss the importance of interference effects for di-Higgs production.
