Atlfast Resolution

Atlfast Resolution. What I do is to get the cuts by studying the Atlfast Resolution. Moustapha used them to set up the cuts for the filter! In my work, I did not study the background. I just assume that the isolation selection in the TDR is right and study the isolated e ’s.

  1. Atlfast Resolution What I do is to get the cuts by studying the Atlfast Resolution. Moustapha used them to set up the cuts for the filter! In my work, I did not study the background. I just assume that the isolation selection in the TDR is right and study the isolated e’s. H->ZZ*->4e (mass=130Gev)

  2. For the Reconstruction of variable “v” we have a cut : the TDR v-cut. While for the filter, generally we make the cut back off from the TDR cut by 3-5 ( is the Atlfast Resolution)

  3. v-cut : with the window around Z mass

  4. In some 4-e’s events, MC has more than 4e’s . We sort the MC e’s by Pt and pick up 4 fastest e’s. Atlfast e’s are already sorted by Pt. So in each event for each “e” we can calculate Among the 4 , we choose the minimum and put it into the histogram. : no position or angle smearing

  5. (1) > 20 Gev: > 7 Gev: (2) Z : (3) Z* : (4) : ~0 There is no smearing of position, only P and E are smeared by the same factor.
