Hi,
our partial BF's for mX and Pplus are much too high. Maybe Roberto
and/or Concezio can give comments to the following:
To cross check Kerstin and I have compared the current mX-q^2 numbers
with what has been obtained for EPS05 (BAD1214) and in BAD913.
There are several puzzles to us which point to the source of the problem
in the efficiency calculation:
Now EPS05 BAD913
eps^u_sel 0.439 0.334 ?
eps^u_kin 0.90 0.955 ?
eps^u_sel*eps^u_kin 0.39 0.32 ?
pstar 1.14 1.204* 1/1.27
where pstar=(eps^u_t eps^u_l)/(eps^sl_t eps^sl_l)
*: only (eps^u_l)/(eps^sl_l)) given
1) Why is there so a large difference in eps^u_sel*eps^u_kin?
2) Why is there so a alrge difference between BAD913 and now?
3) In addition, the pstar factor for the mX analysis is 0.72.
Why is there such a large difference compared to 1.14?
BAD1214 P.31 suggests that there should not be a large
difference.
One should keep in mind that eps^u_l, eps^u_t, eps^u_sel, eps^u_kin
are only for the signal region.
Cheers,
Heiko and Kerstin
