Hi Roberto,
nice work. For the N_u comparison we see the same behaviour, i.e. no
striking differences between run periods as we go from SL to ALLCUTS by
subsequently adding cuts one by one. Since your yields for e.g. SL
events are a factor ~5 bigger than our mES fits on data, I assume that
your numbers are simply event counts, correct? In this case your numbers
contain the combinatorial background as well, so we might be missing any
effect due to mES fits. BTW, did you apply any mES cuts at e.g. 5.27?
Would it be possible to reproduce the numbers by fitting the mES
distributions? (Tedious job, I guess...)
Ciao, Concezio.
