+ Require dileptonic ttbar events at 7TeV. It is important to not include semileptonic decay channels in the runs, as they can not be vetoed in the analysis in a generator-independent fashion but have been subtracted from the particle level measurement. The tau decay channels also count as leptonic.

Description:
'A measurement of the additional jet activity in dileptonic ttbar events. The
fraction of events passing a veto requirement are shown as a function the veto
scale for four central rapidity intervals.
Two veto definitions are used: events are vetoed if they contain an additional
jet in the rapidity interval with transverse momentum above a threshold, or
alternatively, if the scalar transverse momentum sum of all additional jets
in the rapidity interval is above a threshold.'

Description:
'Measurement of the differential t$\bar{\mathrm t}$ production
cross-section in 7 TeV proton-proton collisions in the single-lepton
channel from ATLAS. The data comprise the full 2011 data sample corresponding to an
integrated luminosity of $4.6\,\mathrm{fb}^{-1}$. The differential cross-sections are
measured as a function of the jet multiplicity for up to eight jets using jet transverse
momentum thresholds of 25, 40, 60, and 80 GeV, and as a function of jet transverse
momentum up to the fifth leading jet. The results after background subtraction are corrected
for all detector effects, within a kinematic range closely matched to the experimental
acceptance.'
