------------------------------------------------------------------------------------------------------------------ Speaker: Dr. Andrea Giammanco, Louvain-la-Neuve, Belgium ------------------------------------------------------------------------------------------------------------------ Title: "Study of ttbar dilepton and single top events with the CMS detector" ------------------------------------------------------------------------------------------------------------------ Abstract: This talk discusses the strategies and prospects in CMS for the early observation of the ttbar process using the dileptonic signatures, and of the electroweak single top production in the t-channel and W-associated modes. Emphasis will be given on how to disentangle the cross-contaminations between these different channels, and on data-driven methods to estimate their common backgrounds. ------------------------------------------------------------------------------------------------------------------
