GRID LHCb WP Physics Study
The total sample of B > JY/Ks simulated events needed is ~10 times the number produced in the real data.
In one year of datataking we expect to collect and fully reconstruct 105 events, therefore need 10 6simulated events.
The number of events that have to be generated, stored and reconstructed to produce this sample is 10 7.
10% of the ESD data copied for systematic studies (~100 GB).
The total amount of data generated in this production would be :
RAW data 200 kB/event x 10 7 = 2 .0 TB
Generator data 12 kB/event x 10 7 = 0.12 TB
ESD data 100 kB/event x 10 7 = 1 .0 TB
AOD data 20 kB/event x 10 7 = 0. 2 TB
TAG data 1 kB/event x 10 7 = 0.01 TB
