[Rivet] Rivet plugin ALICE_2014_I1300380

[Enrico Fragiacomo]

Hello Holger,

in the data analysis, the final pT distributions are corrected with the 
Montecarlo for the inefficiencies like those due to the kinetic cuts on 
the daughter particles (and also for the acceptance,...). This is 
described in Section 2.3 in the paper. This holds for those pT bins 
where we are able to extract the signal.

The fact that e.g. for the Sigma(1385) we do not have spectra points 
below 0.7 GeV/c is in fact due to the large inefficiency at low pT which 
makes impossible to extract the Sigma(1385) signal. In order to measure 
the total yield (dN/dy) or the mean pT (<pT>), an extrapolation of the 
spectrum to pT=0 is performed. This is described in Section 3 of the paper.

Does this answer your question?
Thank you.
Enrico
