Training Wbb MC Gen5 vs. Gen6Same Training as ReplicaL4:

- Signal: Wbb Gen5 MC (ltop[0,3]b)- Bkg: Wbb Gen6 MC (btop[0,1,2,5,6,7]w)- Signal:Bkg 50:50- 2 Jets, 1+2 BTag combined- Composition of training tree includes:

- Alpgen X-sections- acceptances

- architecture: 15 hidden nodes- evts in training: about 17K

L4:- Gen6 L5 selection cuts- jets and MET L4-corrected

3

Training Wbb MC Gen5 vs. Gen6Small, but significant separation

4

Training Wbb MC Gen5 vs. Gen6Small, but significant separation

Gen 5 0p and Gen 6 0p are similar

5

Training Wbb MC Gen5 vs. Gen6Small, but significant separation

New Component comes fromadditional Alpen Xp samples

Gen 5 0p and Gen 6 0p are similar
