Abstract

We present a phenomenologic study of some extensions of standard model of elementary particles at LEP and LHC. We concentrate our attention, for instance, on the search of R-parity violating supersymmetry evidences at LEP I, LEP II and LHC. We study a spontaneous R-parity violating model as well an effective one where the violation occurs explicitly. We also perform an independent model study on leptoquarks at LHC coming from e q collisions, in the frame of an effective lagrangian. We show that the effects of these two standard model extensions can be visible in the range of energy of the chosen colliders. (AU)
