Abstract (data abstract)
CERN-LHC. Measurement of jet activity in t-tbar events produced in proton-proton collisions are a centre-of-mass energy of 7 TeV using a data sample of integrated luminsoity 2.05 fb-1. The events are selected in the dilepton decay channel with two identified b-jets from the top quark decays. Events are vetoed if they contain an additional jet with transverse momentum above a threshold in a central rapidity interval. The fraction of events surviving the jet veto is presented as a funtion of this threshold for four different central rapidity interval definitions. An alternate measurement is also presented, in which events are vetoed if the scalar transverse momentum sum of the additional jets in each rapidity interval is above a threshold.
