- W1650872500 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 chi^0_2--> chi^0_1 ll or the 2 body decay chi^0_2-->tilde{l}l at LHC. In the former case, the whole m_{ll} distribution observed at LHC would constrain ino mixing and slepton masses. On the other hand, when tilde{l}l decay is open, the distribution of the asymmetry of the transverse momentum of lepton pair A_T= p_{T1}/p_{T2} peaks at A_E=p_{1}/p_{2} in chi^0_2 rest frame for m_{ll} << m^{max}_{ll} samples, providing another model independent information. The peak position and the edge of the m_{ll} distribution constrain m_{chi^0_2}, m_{chi}^0_1} and m_{tilde{l}}. 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." @default.
