(compare to y=0, abs(zvertex) < 30 has fitable bins 5-28)
Comments
In all cases, the loss of ability to fit is due to kaon contamination.
(ie if we can fix the kaons we can extend our mt-m0 range for all rapidities)
Questions
Why did we cut abs(zvertex) < 30 in the first place?
Is there a way to fix the kaon yields in this range?
Conclusions
Can we get good statistics from higher rapiditiess?
I believe that at least the top 10% centrality data can be extended into y=1.0 without changing the zVertex cut.
If we include all zVertex values we can extend into y=1.2
Is there anything fitable in the relativistic rise?
I looked at the highest mt-m0 bins for all rapidities (bins 30-50) and found no bins which showed fitable seperaion.
