Alpgen Production 2008
- Alpgen ttbar + N partons, N = 0,1,2,3,4
- ptjmin = 30, 40, 50 GeV
- Library: 2Qwork
- Production of grid2 files.
- Maria's rule of thumb: 5+N iterations, where N is the number of light (udsg) partons.
- ~ 43000 events per minute.
Template file:
1 ! generation mode
ttbar4j_40 ! string labeling the output files
0 ! start with: 0=new grid, 1=previous warmup grid, 2=previous generation grid
4000000 5 ! N(events)/iteration and N(iter's) for initial grid optimiz
50000000 ! number evts to generate

- Tried only 5 iterations for ttbar + 4 jets, trying now with 9 iterations and seeing if it makes a difference.

Grids done. Running showering and matching now. Efficiencies seem to come down a little bit too low.
