RunInfo:
'Run MC generators with Z decaying leptonically into both electrons and muons at 7 TeV CoM energy.
Order of 5 million unweighted events can give a reasonable global comparison, but precision in the
high jet multiplicity region/high jet pt may require substantially larger samples or statistical
enhancement of high jet multiplicities.'

Description:
'Measurements of differential cross sections are presented for
the production of a Z boson and at least one hadronic jet in
proton-proton collisions at $\sqrt{s}=7$~TeV, recorded by
the CMS detector, using a data sample corresponding to an integrated
luminosity of 4.9 $\text{fb}^{-1}$. The jet multiplicity distribution
is measured for up to six jets. The differential cross sections are
measured as a function of jet transverse momentum and pseudorapidity
for the four highest transverse momentum jets. The distribution of
the scalar sum of jet transverse momenta is also measured as a function
of the jet multiplicity. The measurements are compared with theoretical
predictions at leading and next-to-leading order in perturbative QCD.
Cuts:
First two leading electrons or muons with $p_T > 20$ GeV and $|\eta| < 2.4$
Dilepton invariant mass in the [71,111] GeV range
Jets $p_T > 30$ GeV and $|\eta| < 2.4$
$\Delta{R}($lepton,jet$) > 0.5$'
