Abstract

We present measurements of DKS0Ï€ and DKL0Ï€ branching fractions using 281pb-1 of (3770) data at the CLEO-c experiment. We find that B(D0KS0Ï€0) is larger than B(D0KL0Ï€0), with an asymmetry of R(D0)=0.108±0.025±0.024. For B(D+KS0Ï€+) and B(D+KL0Ï€+), we observe no measurable difference; the asymmetry is R(D+)=0.022±0.016±0.018. The D0 asymmetry is consistent with the value based on the U-spin prediction A(D0K0Ï€0)/ A(D0K 0Ï€0)=-tana ¡2 C, where C is the Cabibbo angle. © 2008 The American Physical Society.
