Title: Measurement of the CP-Violation Parameter sin(2beta) in B0-> J/psi K-short Decays

Abstract: In the 110 pb^{-1} Run I data sample, using three complementaryflavor-tagging algorithms CDF has made a new measurement of theCP-violating asymmetry sin(2beta)=0.79+0.41-0.44. This corresponds tothe limit sin(2beta)>-0.08 at 95% confidence level. This resultagrees well with predictions from indirect constraints based on fitsof elements of the CKM matrix.
