  Nobody knows exactly what kind of Higgs physics will be unveiled when the
Large Hadron Collider is turned on. There could be one Standard Model Higgs
boson or five Higgs bosons as is the case in two-Higgs-doublet models; there
could be more exotic or even completely unexpected scenarios. In order to be
prepared for the LHC era, a solid understanding of Standard Model or
Standard-Model-like Higgs physics is necessary. The first goal is to discover
the Higgs boson. Afterwards it has to be proven that the new particle is indeed
a Higgs boson. The Higgs boson has to couple to mass and its spin has to be
zero. Additional observables, such as decay width or CP eigenvalue, help to
distinguish between different models. Due to an almost infinite variety of
models, another important goal is to prepare for all possible situations. For
example, Higgs bosons could be produced in decays of heavier particles, or
could decay to invisible particles. In the following, a selection of mainly new
studies by ATLAS and CMS is presented.
