Supersymmetry and Future Colliders
Abstract
In this talk, I review precision SUSY study at LHC and TeV scale e+e- linear colliders (LC). We discuss the study of the 3 body decay of the second lightest neutralino 02--> 01 ll or the 2 body decay 02-->ll at LHC. In the former case, the whole mll distribution observed at LHC would constrain ino mixing and slepton masses. On the other hand, when ll decay is open, the distribution of the asymmetry of the transverse momentum of lepton pair AT= pT1/pT2 peaks at AE=p1/p2 in 02 rest frame for mll << mmaxll samples, providing another model independent information. The peak position and the edge of the mll distribution constrain m02, m01 and ml. Slepton mass universality may be checked within a few % in the early stage of the experiment. Finally I discuss the physics at TeVscale LC. The mass and couplings of sparticles will be measured withinO(1%) error, and measurement of the radiative correction to the ino-slepton-lepton coupling will determine the first generation squark mass scale even in decoupling scenarios.
