dc.descriptionA sample of 400 $B^0_d/\bar{B}{^0_d} \to J/ψK^0_s$ decays collected in $\bar{p}p$ collisions by the CDF detector is used to directly measure the CP-violation parameter $\sin(2β)$. We find $\sin(2β) = 0.79 ^{+0.41}_{-0.44}$,favoring the standard model expectation of a large $CP$ violation in this $B^0$ decay mode.
