Abstract(s) :

(Anglais) In many supersymmetric extensions (SUSY) of the Standard Model, SUSY partners of the 3rd quark generation (stop,sbottom) are lighter than the partners of the 1st and 2nd generations, allowing production rates high enough to be observed at the LHC. Moreover, recent results on Higgs boson searches are in favour of light stop particles. As these 3rd generation SUSY partners should decay to heavy quarks (t,b), evidences for the existence of such SUSY partners might be observed by studying events final-states with top quark pairs or similar to the ones of SM top quark pair production.  We present results from the search for direct production of supersymmetric partners of the top quark with proton-proton collisions at the LHC, using data collected in 2012 by the CMS detector.
