Search for Supersymmetry in top final states at CMS

Ms. Narges Salimi from Tarbiat Modarres University

 Abstract: The discovery of the SUPERSYMMETRY is one the main goals of the Large Hadron Collider being built at CERN. Supersymmetry imposes a new symmetry between the fermionic and bosonic degrees of freedom. Here we consider a very constrained scenario where gravity is responsible for SUSY breaking. This model is called mSUGRA. A two constraint kinematic fit is utilized to extract the top quark, for both state that can recognize b-jet and can not recognize it. The capability of CMS to find low mass SUSY in events with a top quark in the final state was studied by full simulation . It is shown that for point LM1, for analysis that can recognize b-jet , with an integrated luminosity of 30 pb-1 and for analysis that can not recognize b-jet, with an integrated luminosity of 9.6 pb-1, a 5 discovery is achievable provided the uncertainty is statistics dominated. The final signal over background ratio, for both states, is 12.0.
