Running from TMBTree's

• For selection macros, see MuTag.h, MuTag.C  in /prj_root/809/b_1/rickv1/runtmb
• For clear instructions on how to run on TMBTree's in root, see Serban's README.txt in (addpkg -h tmb_analyze) ~/tmb_analyze/macros   "Snapshotted" here for your convenience: p13.02 p13.04

 
• e.g. after following the above, in root session:

 .x LoadTMBTree_so.C
 .L MuTag.C++  (to make a shared object)
  MuTag t("filename_tmbtree.root")
   e.g., to run on one of the mujet TMBTree's in that directory,
    MuTag t("mujets_3056_tmbtree.root")
  t.Loop();

Data Files

• original TMBTree files from Top group's mujet skim: prj_root/809/b_1/rickv1/runtmb/mujets_xxxx_tmbtree.root

 
• selected TMBTree events from Top group's p13.02 mujet skim, starting with 3M events

 
• Total no. events: ~25k, demanding dR < 0.7 mu-jet association and tight global muon (p13 muonid, Saclay matching). No pt_rel cut on muon, good for i.e., doing pt_rel fits using whole range for e.g., lifetime tag certification): indiana-clued0:/rooms/living/rickv/p13_mujets/no_ptrelcut

 
• Total no. events: ~11k, demanding dR < 0.7 mu-jet association and tight global muon and pt_rel(muon) > 1.0 GeV cut (greatly enhanced in b-content. Estimate ~70% b events):
