ttbar Selection in Gen5

Last update 02/18/2005

• Data used: data untill August shutdown (run range: 138425 - 186598) . Run 164844 is excluded.
• Topntuples used: topnt_top_533_nt5_*sample*_*section*-Lepton.root located in fcdfdata128.fnal.gov//export/data4/top/TopNt/*sample*/
• Numbers and distributions of all the variables used in the ttbar selection:

Sample	Plots for All files	First file	Last file	All files
bhel0d	Click here	Section 1	Section 476	All
bhmu0d	Click here	Section 1	Section 123	All
bhel0d + bhmu0d	-	-	-	All

• A jet is tagged if it is taggable and it has positive JetProb < 0.01.
• List of the candidate events with, at least, one positive tagged (SecVtx or  JP).
• Numbers and list of the candidate events running only over data untill September 03 shutdown. To make easier the comparison, we do not require taggability and we remove runs 163463 and 163474 as it was done in Gen4 (Numbers in brackets correspond to Gen4). Plots for the electron and muon sample.
