Three extensions of the scalar sector of the Standard Model are considered: one extra isosinglet, one extra isotriplet, two extra isotriplets (the Georgi-Machacek model). Double Higgs boson production cross section is calculated in all these extensions. Bounds from electroweak precision observables, signal strength measurements and custodial symmetry violation are estimated.
