Hi all,
I checked the number of neutrals that are identified as true KLs and
whose energy is rescaled by ~20%.
On:
- cocktail MC
- recoil neutrals
- b->clnu events
I got that the ~3% of the neutral deposits passing our quality cuts is
associated to true KLs.
The number of events with KL's is ~25% of the total.
The KL "efficiency" is ~25% and it is not due to MC matching but
entirely due to our quality cuts on the single neutral. If I try to
count before the cuts on the single neutral deposit the KL
efficiency is ~95%.
Then the message is: it looks like we are applying the correction to the
right number of Kl's but they rapresent only the 3% of the neutral
deposits.
Alessio, are these numbers similar to yours? assume that I am not
applying any event-based cut.
