New Phenomena Beyond Both the Standard Model and MSSM 1 2

The Standard Model (SM) is in complete agreement with present experimental data. Nevertheless, it is believed to leave many questions unanswered, and this belief has resulted in numerous attempts to nd a more fundamental underlying theory. One key ingredient in the extrapolation of the SM to higher energies is to identify the complete particle spectrum at the electroweak scale. Two popular examples of theories which populate the TeV scale with a plethora of new particles are supersymmetry and technicolor. This has resulted in extensive searches for superand techni-particles, which have been reported elsewhere at this meeting (1). In this talk, I will identify other possible manifestations of new physics, and discuss their implications on hadron collider physics.
