Model-independent measurement of t-channel single top quark production in pp? collisions at s=1.96 TeV
Original language description
We present a model-independent measurement of t-channel electroweak production of single top quarks in /ppbar collisions at s=1.96//TeV. Using 5.4//fb1 of integrated luminosity collected by the D0 detector at the Fermilab Tevatron Collider, and selectingevents containing an isolated electron or muon, missing transverse energy and one or two jets originating from the fragmentation of b quarks, we measure a cross section ?(/ppbar/rargaptqb+X)=2.900.59//(stat+syst)//pb for a top quark mass of 172.5//GeV.The probability of the background to fluctuate and produce a signal as large as the one observed is 1.6108, corresponding to a significance of 5.5 standard deviations.
