Evidence of s-channel Single Top Quark Production in Events with one Charged Lepton and Bottom Quark Jets at CDF

Abstract

We report an evidence of \textit{s}-channel single top quark production in $p\bar{p}$ collision at $\sqrt{s}=1.96\mathrm{TeV}$ using data with integrated luminosity of $9.4{\mathrm{fb}}^{-1}$ collected by the Collider Detector at Fermilab (CDF). We select events with one charged lepton, large missing transverse energy and two bottom quark jets. The observed significance of the result is 3.8 standard deviation from background only prediction. We measure the inclusive cross section to be $1.41_{-0.42}^{+0.44}(\mathrm{stat}+\mathrm{syst})\mathrm{pb}$ assuming $m_t=172.5\mathrm{GeV}/c^2$.
