Comparisons to CLEO and E791
The comparison to CLEO is only valid if one assumes a small strong phase difference ?
We have essentially the same sensitivity to the CLEO CP constrained fit but are getting the opposite sign!
yCP = 3.42 ? 1.39 ? 0.74 %
E791: yCP =(+0.8 ? 2.9 ?1)%
CLEO -5.8 % < y’ < 1% (95% CL)
