Query: Double Higgs boson production in the Standard Model with extra scalar
  particles   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.
