Several new physics models predict that new heavy particles may exist and be produced at the LHC. For the first time, the collision energy is high enough that these particles may be so heavy that they can decay into lighter final states including W/Z/h bosons and top quarks. These models, including supersymmetry (SUSY) may provide answers to questions such as the hierarchy problem (i.e. why do the forces that we know of have such a large range of strengths?) or what is the dark matter.
