Run-11 Transverse Jets: Detector-jet-to-Parton-jet Matching Fractions

Updated on Sat, 2014-08-02 18:33. Originally created by drach09 on 2014-08-02 18:25.

Here, I post the updated matching fractions, now, using the "nominal+3" trigger threshold scheme.

Table 1

  VPDMB JP0 JP1 JP2
pT BIN [GeV/c] TOT MID FORWARD TOT MID FORWARD TOT MID FORWARD TOT MID FORWARD
5-6 0.582 0.569 0.602                  
6-7.1 0.660 0.674 0.635                  
7.1-8.4 0.783 0.766 0.817 0.697 0.630 0.913            
8.4-9.9 0.639 0.553 0.863 0.732 0.718 0.753            
9.9-11.7 0.907 0.930 0.864 0.918 0.882 0.961 0.864 0.806 0.921      
11.7-13.8 0.965 0.984 0.936 0.998 0.999 0.997 0.998 0.997 0.998      
13.8-16.3 0.998 0.998 0.997 0.998 0.9997 0.994 0.997 0.9995 0.990      
16.3-19.2       0.999 0.9997 0.998 0.999 0.999 0.999 0.998 0.997 1
19.2-22.7       0.9996 0.999 0.9999 0.9999 0.99998 0.9999 0.99995 0.9999 0.99998
22.7-26.8       0.99999 0.99998 1 0.99999 0.99998 1 0.99997 0.9999 1
26.8-31.6       0.999 1 0.998 0.999 1 0.998 0.999 1 0.997
31.6-37.3       1 1 1 1 1 1 1 1 1
37.3-45       1 1 1 1 1 1 1 1 1
45-55       1 1 1 1 1 1 1 1 1
55-65       1 1 1 1 1 1 1 1 1
65-80       1 1 1 1 1 1 1 1 1

The largest difference is that the 8.4-9.9 GeV/c matching fraction for JP0 (noted in blue) is vastly improved. This is likely a result of the "+3" scheme dropping an unmatched jet or two from the lower partonic pT bins. All other changes are modest, and likely simply statistical fluctuations. Changes with a few percent drop are noted in red.
