Minutes

• Report is due Sep. 2nd to the Prod. & Analysis meeting
• CDC correction is now in the master.
  • A file in use with the updated dEdX is not run dependent, but it does reduce the gain by about 5%.
  • Alexander reports a rho yield decline of order 10% for the fall data
• Foda reports his finding for the special production with wide analysis cuts using Justin's scripts.
  • Matt suggests to also look at bggen MC data where background plays a more important role as compared to signal MC.
  • Foda just reported in the Q&A meeting that the wrong plots were uploaded (narrow cuts instead of wide timing cuts)
• A look at Mahmud and Colins work was done to compare with Foda's findings.
