We have studied the possibility but we obtain a better significance by |
| 55 |
|
applying a cut on transverse mass of W candidate ($>$50 GeV). In the |
| 56 |
|
analysis we are now considering such cuts. The studies of the |
| 57 |
|
different angle proposed have been also performed but the transverse |
| 58 |
|
mass remain the best variable. DO YOU HAVE PLOTS? |
