Abstract:
I shall discuss two aspects of an extended Higgs sector, not imposing
supersymmetry. First of all, a Higgs sector extended with one or
more doublets implies the existence of charged Higgs bosons. An
extensive experimental program is aimed at searching for these, but
there are many constraints making the search difficult. Secondly, an
extended Higgs sector allows for CP violation in the Higgs sector. This
is very attractive, as it facilitates baryogenesis. Physical conditions
for such CP violation will be discussed.
