Hi all,
I reoptimized the cut on Mx with:
- new theo error using mb=4.80+-0.09 GeV (instead of +-0.0150MeV) and
including systematics on the eps_u efficiency
- all exp systematics included. I put there only the ones dependent on
Mx. They are K+, Klongs, tracking, neutrals (where I assume that they
affect only the backgrounf) and B/D systematics.
This is the result:

and the new "best" cut is Mxcut=1.63GeV.
