Extensions of the scalar sector predicts the existence of new scalar bosons. The searches for
two interesting processes motivated simple extension of the scalar sector, the two-Higgs-doublet
model, are reviewed. The first process is the production of a pseudoscalar decaying into a Z boson
and a light Higgs and the second process is the production of a heavy Higgs scalar decaying
into a pseudoscalar and a Z boson. While involving similar final states, these searches probe
complementary parameter space. In particular the second is sensitive to the alignment limit in
which the lightest scalar behaves as the standard model Higgs boson.
