testProduction_Analysis_compare_to_run12

 Questions raised: 

  • What caused for the differences between blue(p12ic) , red (p13ib) and green(test)  points in the efficiency plots?




  • Is there any tpc dead sectors? if so is the calibration has been done to recover those sectors ?
  • What is the run List  selection criteria  for the final production?

1) before find out what is the difference between  test production and any other,  First WHAT CAUSE THE DIFFERENCE BETWEEN BLUE  AND RED POINTS?

                                                   BLUE   -------------------------------->          RED
 
a) tpc Calibration:                     NOT complete---------------------------->     complete                        
b) PPV version:                           default--------------------------------->     modified PPV 2

 


2) Now for the run- 13 test Production , we use the same PPV vetex finder as p12ic with complte and improved  TPC calibration copared to p13ib. WHAT CAUSE THE DIFFERENCE BETWEEN BLUE AND GREEN POINTS TOWARDS HIGH ZDC RATE:

Possible reasons:

a) PPV version used 
b)TPC dead sectors
c) Unceternity related to Luminosity calculation for run 13- test

*******************************************

What can we do to analyze these reasons:

1) Reproduce a test sample ( only using runs which have higer ZDC rates (312-433)kHz, with the improved PPV 2 .

Current status: We started reproducing MuDsts from 183 daq files using the runs  which have higer ZDC rates (312-433)kHz.   production details :  column 5 above table.

2) Investigate  and compare TPC dead sectors in  run 12 productions vs run 13.

TPC dead sectors: run 12 vs run13 test

3) reproduce the page 1 "cuts plot" for run12 each production and run 13 using the runs within the higher ZDC rate range (313-433)kHz and find out which cut is impacting by higher Luminosity rates
