Book Description
The CP-violating parameter sin 2[beta] is directly measured using 110 pb[sup[minus]1] of data accumulated with the CDF detector at the Fermilab[anti p]p Tevatron collider operating at[radical]s= 1.8 TeV. The signal consists of 395[+-] 31 B[sub d][sup 0][r[underscore]arrow] J/[psi] K[sub s] events. Three tagging methods are used to identify the type of B meson at production (B[sub d][sup 0] or[anti B][sub d][sup 0]). From the CP asymmetry, sin 2[beta] is measured to be 0.79[sub[minus]0.44][sup+0.41], consistent with Standard Model predictions. Sin 2[beta] is in the interval 0[lt] sin2[beta][lt] 1 at the 93% confidence level.

Book Description
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.

Book Description
A sample of[approximately] 400 B[sub d][sup 0]/[bar B][sub d][sup 0][r-arrow] J/[psi]K[sub s][sup 0] decays collected in[bar p]p collisions by the CDF detector is used to directly measure the CP-violation parameter sin (2[beta]). They find sin(2[beta])= 0.79[sub[minus]0.44][sup+ 0.41], favoring the standard model expectation of a large CP violation in this B[sup 0] decay mode.

Book Description
The authors report a measurement of the CP-violation parameter sin2{beta} with B{sup 0} {yields} J/{phi}K{sub S}{sup 0} decays in which the J/{psi} decays to hadrons. With a sample of 88 million B{bar B} events collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC, they reconstruct 100 {+-} 17 such events, with J/{psi} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0} being the most prevalent, and measure sin 2{beta} = 1.56 {+-} 0.42(stat.) {+-} 0.21(syst.).

Book Description
The most recent results from the B-factories on the time-dependent CP asymmetries measured in B°-decays mediated by b → c{bar c}s quark-transitions are reviewed. The Standard Model interpretation of the results in terms of the parameter sin 2[beta] leads to a four-fold ambiguity on the unitarity triangle [beta] which can be reduced to a two-fold ambiguity by measuring the sign of the parameter cos 2[beta]. The results on cos2[beta] obtained so far are reviewed.

Book Description
Since the first observation in 1964, CP violation remains one of the most elusive aspects of the standard model. The CDF collaboration has reported the first evidence of CP violation in the B system using the world's largest sample of B → J/[psi]K{sub S}° decays. The direct measurement of sin(2[beta])=0.79{sub -0.44}{sup +0.41} (combined statistical and systematic error) agrees with the standard model predictions. New data collected from the B-factories and from the upgraded experiments at the Tevatron should allow a more precise measurement of sin 2[beta] in the near future.
