| ===== Motivations ===== | ===== Motivations ===== | ||
| - | * defining a format sample for jet-clustering output (without fast-simulation detector). | + | * defining a format for jet-clustering output (without fast-simulation detector). |
| - | * LHCO contains too few information for performing sophisticated analysis. Need to add more variables. | + | |
| - | * LHCO does not take into account all Delphes3 potential. | + | * defining a format which extends the LHCO content (too few information for performing sophisticated analysis). |

| + | * the new format will take into account all Delphes 3 potential. | ||
| ===== Some ideas to discuss ===== | ===== Some ideas to discuss ===== | ||
| - | * Name of the format extension: eLHE (e for 'extended') ? | + | * Using text format (theorist-friendly format :-D). ROOT is rejected. |
| - | A small example | + | * Prefering extending an existed formt to defining a totally new one (avoiding coding writer and reader functions from scratch). Our choice is to extend the LHE Format (arXiv:hep-ph/0609017) and its structure based on XML tags. Reminder about the LHE structure: |
