Here I present the results of the MuDst based QA of the 2009 FF reproduction test sample ...

I have processed 90 runs from the old FF production (P10ic) and from the new FF production (P11id). I have also processed 40 runs from the old RFF production for comparison.

To test whether or not the new production of the 2009 FF data took care of the high pt track problem I had seen in the original production, I have done a MuDst based track QA. For the plots below, I look at all primary tracks from the first primary vertex in events which fire either the L2JetHigh or JP1 triggers and pass the following cuts:

• track flag > 0
• # of Hits > 12
• # Hits / # Possible Hits >= 0.51
• 0 <= chi2 <= 4.0
• pt > 0.2 GeV
• -2.5 <= eta <= 2.5
• 0.0 <= TDCA <= 3.0
• Pt Dependant DCA cut

Figure 1: This plot shows the track phi vs the charge signed track pt. The upper left pannel is for the original FF production, the upper right pannel is for the new FF production, and the lower pannel is for the original RFF production. The pathology in sector 20 (phi between 0 and -1) is clearly visible in the upper left plot and is gone in the upper right.

Figure 2: This plot shows the track phi vs eta. The upper left pannel is for the original FF production, the upper right pannel is for the new FF production, and the lower pannel is for the original RFF production.

Figure 3: This figure compares the old FF track pt to the new FF track pt in sector 20. The top left pannel shows the positive charge sign spectra and the top right pannel shows the negative charge sign spectra. Blue curves are the old FF production and red curves are the new FF production. The bottom pannels show the old / new ratio.

I have a PDF with analogous plots to the one in figure 3 for all 24 TPC sectors.

I have also created a PDF which compares the Original RFF production with the Old FF production for all 24 TPC sectors for reference.

Finally, I have created a PDF with plots for all 24 TPC sectors which compares the Original RFF production with the new FF production to see how the new production compares to the relatively good Original RFF production.

Figure 4: This figure shows the h-/h+ spectra and ratios for the old FF production (left pannel) and new FF production (right pannel) for sector 20. Negative charge sign tracks are in Blue and positive are in Red.

Figure 5: This figure shows the h-/h+ spectra for tracks in the East (upper left pannel) and West (upper right pannel) TPC along with the h-/h+ ratios (lower left pannel). The Blue spectra are negative charge sign tracks, the Red are positive tracks, the Black points are for the East TPC tracks, and the Green points are for the West TPC tracks. This is for the Old RFF sample

Figure 6: Same as figure 5 but for Old FF production.

Figure 7: Same as figure 5 for New FF production.
