The author reviews the history and present status of CP violation measurements made during RunII of the Fermilab Tevatron. Both flavor-tagged and untagged measurements of the Cp-violating phase [beta]{sub s}{sup J/[Psi]} are discussed, as well as measurements of the width difference [Delta][Lambda]{sub s} between heavy and light B{sub s}° mass eigenstates made in the B{sub s}° → J/{Psi}[phi] system.

We present six time-dependent B0d mixing measurements of [Delta]md from the CDF Run I data. The CDF average is [Delta]md = .494".026".026(ps)-1. We also present a measurement of the CP-violating asymmetry sin(2[beta]) using a sample of B0/[anti B]0 [yields] J/[psi] K0s decays and report sin(2[beta]) = .79 +41-.44.

The authors present six time-dependent B[sub d][sup 0] mixing measurements of[Delta]m[sub d] from the CDF Run I data. The CDF average is[Delta]m[sub d]= .494[sub[+-] 0.26][sup[+-] 0.26](ps)[sup[minus]1]. They also present a measurement of the CP-violating asymmetry sin (2[beta]) using a sample of B[sup 0]/[bar B][sup 0][r-arrow] J/[psi]K[sub s][sup 0] decays and report sin(2[beta])= .79[sub[minus].44][sup+.41].

We have made a preliminary study of a dimuon sample corresponding to 114 pb{sup -1} of data taken in Run II at the Tevatron. From this sample we have selected 157 {+-} 20 B{sub d} {yields} J/{psi}K{sub S}{sup 0} and 133 {+-} 17 B{sub s} {yields} J/{psi}{phi} decays. In a subset of the data we have measured the B{sup {+-}} lifetime in the J/{psi}K{sup {+-}} channel to be 1.76 {+-} 0.24 ps. We have implemented a jet-charge initial-flavor tag as well as a soft-muon tag, and we have measured the respective tagging powers to be (2.4 {+-} 1.7)% and (3.3 {+-} 1.8)%. Our conclusion from these studies is that we have made good progress towards understanding all ingredients required to make CP violation measurements in the B{sub d} and B{sub s} systems.

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.
