Abstract: (APS)

We have measured the branching ratio for KL0→μ+μ− using our full data set obtained during running periods in 1988, 1989, and 1990. The total number of μ+μ− candidates after a background subtraction is 707, which represents the largest sample to date of this rare decay mode. Our result is B(KL0→μ+μ−)=(6.86±0.37)×10−9, which is consistent with earlier results and very near the unitarity bound. The upper limit on B(KL0→μ+μ−) is used to set an upper limit on the real part of the amplitude scrA(KL0→μ+μ−); this is subsequently used to constrain the top quark mass mt and the Wolfenstein parameter ρ of the CKM matrix.
