1.  K K L  +

3.  + component, ME  + component, LE Difference

4. Nubar-PID performance on L100200 So carried out idea…

5. L010185 L100200 data rw-MC data rw-MC data and MC rw-MC (L100200-L010185) data (L100200-L010185)

6. (no  +), LE (no  +), ME ratio diff L010185 and L100200 MC (reweighed)

7. 1 st try: fit the ME-LE data with the following function: Simple chi-squared used for the fit: where:

8. 1 st check: Fit for (ME-LE) MC after correcting for ME,LE differences with the MC: ME-LE, no  + (MC) (ME-LE) MC Fit  parME and parLE indeed converge at 1.0

9. 2 nd check: Fit for (ME-LE) MC assuming no ME,LE differences besides  +: parLE = 0.728±0.591 parME= 1.303±0.297 Fit values: (ME-LE) MC Fit

10. Now fit for (ME-LE) DATA assuming no ME,LE differences besides  +: parLE = 2.623±0.847 parME= 0.703±0.436 Fit values: (ME-LE) DATA Fit

11. Fit (ME-LE) MC again with less bins: parLE = 0.195±0.587 parME= 1.015±0.290 Fit values: (ME-LE) MC Fit

12. parLE = 1.793±0.861 parME= 0.477±0.431 Fit values: (ME-LE) MC Fit Fit (ME-LE) DATA again with less bins:

13. BACKUP
