Hi all,

About a few months ago, I summarized the pi0 fit results (peak positions, peak widths) for all pt-, centrality ranges from the working group websites as attached, which shows quite large (systematic?) fluctuations - you may play the presentation show. How can we understand it? I would like to suggest to start these fundamental results of mass_inv, before we go to the main results with their yields.
