Searching for the Higgs and other Exotic Objects: A "How to" Guide from LEP to the LHC

Methods and ideas to search for new phenomena at existing and future collider facilities like LEPII and the LHC are analysed. Emphasis is put on the experimental aspects of discovery strategies for the Higgs Boson of the Standard Model. This is followed by a critical analysis of search methods for the extended Higgs sector and the direct detection of Supersymmetric Particles within the Minimal Supersymmetric Standard Model. We also discuss methods and the potential mass reach of the LHC experiments to discover new Bosons and Fermions.
