% Z+jets cross section measurement
% 
% Measurements of the jet PT dependence of the Z+jets cross section.
% for the following kinematic range:
% - ET(jet)>30 GeV, |eta(jet)| < 2.1
% - ET(e)>25 GeV (for both electrons)
% - |eta(e1)|<1.0, |eta(e2)|<1.0 or 1.2|eta(e2)|<2.8 (i.e. one electron with |eta|<1 and a 2nd electron
%   with either |eta|<a or 1.2<|eta|<2.8)
% - 66 < m(ee) < 116 GeV/c^2
% - delta(R(j,e))>0.7 (any electron is separated from the jets by >0.7
%
% The measurement is made at hadron jet level, i.e. the data are not corrected
% for hadronisation effects to be compared to partons. The correction for correcting
% parton level calculation to hadron level was evaluated also and is given separately below.
%
% Note that the cross section measured vs Et for >=1 jet actually contains all jets from events
% with >=1 jet. I.e. a 2-jet event has two entries etc. The same applies to the x-sections for >=2 jets etc.
%
% the measurement includes the gamma* component and the Z/gamma* interference within the 
% mass range of 66<m(ee)<116 GeV
%
% The details of the analysis can be found in arXiv:0711.3717
