In the 110 pb{sup -1} Run I data sample, using three complementary flavor-tagging algorithms CDF has made a new measurement of the CP-violating asymmetry sin(2{beta})=0.79{sup +0.41}{sub -0.44}, This corresponds to the limit sin(2{beta})>-0.08 at 95% confidence level. This result agrees well with predictions from indirect constraints based on fits of elements of the CKM matrix.
