Measurement of the single top quark t-channel cross section with a template fit analysis Mario Merola for the CMS Collaboration Abstract We present a measurement of the inclusive single top t-channel production cross section in protonproton collisions at the LHC, using data collected with the CMS experiment during 2011 and 2012. The analyzed data correspond to an integrated luminosity of 1.17/1.56 fb −1 for muon/electron channel respectively at the centre-of-mass energy of 7 TeV, and to 5.0 fb

The analysis exploits the pseudorapidity distribution of the recoil jet and reconstructed top-quark mass using background estimates determined from control samples in data. The measurement is used to determine the CKM matrix element |V tb |. Abstract.
