Improving the Acceptance in the Single Top Quark Analysis using 7.5 fb$^{-1}$ of CDF data

Abstract

The Top quark was observed at the Fermilab Tevatron by the CDF and D0 collaboration in 1995 via strong production of top quarks pairs at center-of-mass energy of $ \sqrt{s}=1.8 $ Tev, using 60 pb-1 of data [1]. Standard Model of elementary particles predicts top quark to be produced individually via electroweak interactions in three different channels (s, t and Wt). This is defined as ”single top” (from now on also ST). ST was observed by CDF collaboration in 2009 at center-of-mass energy of $ \sqrt{s}=1.96 $ Tev using 3.2 fb-1 of $ p\overline{p}\ $ collected data [2]. This thesis concerns the upgrade of this measurement using 7.5 fb-1 of data.
