UNSPECIFIED (2014) Measurement of differential tt production cross sections in pp collisions. Physical Review D, 90: 092006. ISSN 1550-7998
Abstract
The production of top quark-antiquark pair events in pp¯ collisions at s√=1.96 TeV is studied as a function of the transverse momentum and absolute value of the rapidity of the top quarks as well as of the invariant mass of the tt¯ pair. We select events containing an isolated lepton, a large imbalance in transverse momentum, and four or more jets with at least one jet identified as originating from a b quark. The data sample corresponds to 9.7 fb−1 of integrated luminosity recorded with the D0 detector during Run II of the Fermilab Tevatron Collider. Observed differential cross sections are consistent with standard model predictions.
