Hello again, <br>
<br>
David was the main actor for the Pythia simulation at the time of
the paper.<br>
We exchanged a few mails over the last days, to check we understand
similarly again our own developments.<br>
<br>
Among other things, Pythia 6 tunes Z1, Z2, Perugia 2011 simulations
were carried out.<br>
Pythia 8 was not tried at that time.<br>
Perugia 2011 was the one of best performance so became the one we
focused on.<br>
<br>
<br>
<u>About the Pythia generation and analysis :</u><br>
<br>
- there is no special thing with the .cmnd config file.<br>
The central tune Perugia 2011 (350) was used as it is.<br>
The simlulated events are only "inelastic" ones (i.e. allow for
single+double diffraction on top of the non-diffractive processes).
<br>
<br>
- The MC analysis was performed via ROOT+TPythia6, so that TH1 can
be used.<br>
<br>
<br>
<u>MC points</u> <br>
<br>
<br>
I enclose the table of values, taken from our macro to produce Fig.2
in <a class="moz-txt-link-freetext"
href="http://arxiv.org/pdf/1204.0282v2.pdf">http://arxiv.org/pdf/1204.0282v2.pdf</a>.<br>
- David is certainly ashamed that I show the underwear of his old
code ( :-) ) but ok, let me give you some clarification in the
naming of things.<br>
<br>
1. You will see Z2 in every array name but has no meaning (except
for Z2 tune values...)<br>
<br>
2. The pt binning of ALICE data was used.<br>
There are MC points simulated with the Xi binning (= 18 pT bins)
and this also for the Omega spectra, and conversely, MC points with
Omega binning (= 8 pT bins) also for the Xi spectra.<br>
Which binning is used where is indicated by the first particle
name next to Z2, e.g. Z2<font color="#cc0000">XiSimulated</font>XiMinus<br>
<br>
3. the Pythia values corresponds here to the integral of counts over
each pT bin width = a bin content in the ROOT sense.<br>
Note these values ARE already further divided : <br>
- by Delta(pT), the pT bin width, i.e. normalised by unit of pT.<br>
- by the number of PYTHIA INEL events analysed<br>
<br>
4. As a consequence of these normalised integral of counts,<br>
4.1 - the division of MC/data is kept straightforward<br>
4.2 - No need to worry about the right pT place to display the
ratio MC/data (cf. Lafferty-Wyatt NIM paper) : the points are
displayed at the centre of the pt bins.<br>
<br>
<br>
<br>
<u>Comparison CMS/ALICE</u><br>
<br>
About the comparison of Xi+-(CMS) and Xi+-(ALICE), I enclose an
exchange I had recently with Andreas on the topic.<br>
The main point is NSD/INEL and the fact that CMS is not only Xi- but
the sum of Xi- and anti-Xi+<br>

href="http://mcplots.cern.ch/?query=plots,ppppbar,uemb-soft,Xim_pt">http://mcplots.cern.ch/?query=plots,ppppbar,uemb-soft,Xim_pt</a>
<br>
That CMS plot should maybe be moved next the ALICE 900 GeV (Xi-+Xi+)
results<br>

We stay at disposal.<br>

<div class="moz-cite-prefix">Dear Boris and ALICE collaborators<br>
<br>
First of all thank you for providing the Rivet analysis, I have
already tried to run it to test how the new model compares (but
I need a bit more time before I am going to discuss that in
details :)).<br>
<br>
I have also tried to compare this analysis with the Xi
production measured by CMS (CMS_2011_S8978280), and the
models/data seems to be quite different (the two analysis
differs in that one is NSD, where as yours is fully inelastic).
But before drawing any conclusions, I would first like to test
whether I use the analysis correctly. I was therefore wondering
if you have the MC data that is shown in the article available
in a table format? That way I would be able to run Pythia with
the same tune and verify that I can get the same result as is in
your article (if you already did this, it is of course not
needed for me to do it). Otherwise if you for some reason still
happen to have the Pythia .cmnd file you used to generate the
events used in the article laying around, I would be very happy
if you could send me that (I know this is probably a bit too
much to ask).<br>
<br>
Best regards<br>
Jesper<br>
