That makes sense. I wonder nothing really has changed in the code
since then.<br>

Peter, would you be able to run H++ with an earlier version of rivet
to<br>
see if there is the same discrepancy or not?<br>

<br>
So I was comparing the results
with the latest version of Heriwg++
as part of our testing before the
next release and we were much
further off than I expected. After
looking at the analysis and the
paper I believed the paper was
plotting d sigma /dy/dpT and the
analysis d sigma/d|y|/dpT which
differ by the factor of 1/2. I
contacted Vojtech and he agreed it
was wrong so I made the change.<br>
<br>
If it is wrong we can change it
back<br>

<div>Dear Rivet authors, </div>
<div><br>
</div>
<div>it looks like a bug has
been introduced in the
current trunk version of the
ATLAS inclusive jets
measurement (the version
from the last release is
fine). Specifically, the
normalisation factor in the
finalise routine has been
modified:</div>
<div><br>
</div>
<div><a moz-do-not-send="true"
href="https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2014_I1325553.cc#L83"
target="_blank">https://rivet.hepforge.org/trac/browser/src/Analyses/ATLAS_2014_I1325553.cc#L83</a><br>
</div>
<div><br>
</div>
to include an additional
factor of 0.5 -- apparently to
fix an issue with the
normalisation.
<div><br>
</div>
<div>There should be no such
factor as absolute rapidity
has been used consistently
throughout the analysis and
such a factor is only really
necessary if absolute and
signed rapidities are being
mixed (axis label vs cross
section differential).
<div><br>
</div>
<div>Note that the original
version (without 0.5) has
been validated and no
issues with the
normalisation have been
observed, so I would
recommend to unfix this
again. :-)<br>
</div>
<div><br>
