Abstract
The present thesis presents two different acpects of my work in the L3 experiment, which are<br />on one side the search for supersymmetric particles, the scalar leptons, in two different topologies :<br />" electron + X + Ebar " and " 2 leptons + 2 photons + Ebar ", each of them being related to two theoretical SUSY models, m-SUGRA and GMSB. On the other side my work has been completed by<br />the study of the BGO cristal electromagnetic calorimeter of L3, and the calibration of the electromagnetic calorimeter EGAP. After the essential motivations being reviewed, the production and<br />desintegration modes are detailled concerning the scalar lepton sector at L...
