| This thesis explores two aspects of supersymmetric phenomenology at the Tevatron collider at Fermilab and the Large Hadron Collider at CERN. We begin by studying the expected capabilities of these colliders to discover or exclude the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM). We provide a detailed analysis of the MSSM Higgs sector physics that leads to varying prospects in different regions of parameter space, and examine the complementarity offered by the combined reach from multiple search channels. In the second part of the thesis, we study from a new angle the problem of deducing the high-scale properties of supersymmetry (SUSY)-breaking from TeV-scale mass measurements. We consider a set of 1-loop Renormalization Group invariant (RGI) functions of the MSSM parameters and describe procedures by which the RGIs may be used to easily constrain the input parameters of many SUSY-breaking models. |
