Conclusions

The results of comparison among 13b, 13c and All showed that there is a fluctuation in the mean and sigma from the fits. The values are compatible within one uncertainty. 13b shows a bit variation, but it can be justified by lower statistics.

The comparison between pKpi and piKp shows that piKp seems to contain slightly narrower sigma. The results are compatible within uncertainties though, except to 3-4 GeV/c bin. Nevertheless, due to the uncertainties from Real data analysis, the small difference between the results will not be significant for a comparison data x simulation. However, one needs to investigate if there is any reason why the issue in 3-4 appeared.
