Single Top production at CMS
Abstract
A first measurement of the cross section of single top quark production in the t channel in pp collision at sqrt(s)=7 TeV is presented. The measurement is performed on a data sample corresponding to an integrated luminosity of 35.9 pb^-1 recorded at the LHC with the CMS detector. Leptonic decay channels with an electron or a muon in the final state are considered. After a selection optimized for the t-channel mode, two different and complementary analyses have been performed. Both analyses confirm the Tevatron's observation of single top, and their combination measures a cross section of sigma = 83.6 +/- 29.8(stat.+syst.) +/- 3.3 (lumi.) pb, which is consistent with the Standard Model prediction.
