This thesis describes a measurement of a CP violating asymmetry in neutral B meson decays, B° yields D{sup *0}h°, where D{sup *0} is a charmed meson and h° is a light meson, performed on data collected by the BABAR experiment at the SLAC asymmetric-energy electron-positron collider PEP-II.

Detailed measurements of CP violation in B meson decay are on the horizon. Here the author reviews the status of current measurements of sin 2[beta] made at LEP and CDF. These yield an average of sin 2[beta]= 0.82[+-] 0.39, giving 97% confidence that[beta] is greater than 0, evidence that CP violation occurs in B decay. He reviews predictions for the precision one can expect on sin 2[beta] and sin 2[alpha] in the next few years.

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.

We present a preliminary measurement of the time-dependent CP-violating asymmetry in the neutral B decay B° →?K{sub s}°, with? → KK− and K{sub s}° →?+?−. The measurement uses a data sample of about 87 million?(4S) → B{bar B} decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. In this sample we study events in which the CP final state is fully reconstructed and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry sin2? is derived from the decay-time distributions. We measure sin2? = -0.19{sub -0.50}{sup +0.52}(stat) ± 0.09(syst).

The CP violation is explained in the Standard Model with three quark generations with an irreducible phase in the Cabibbo-Kobayashi-Maskawa quark mixing matrix. The unitarity of this matrix can be represented in a complex plane as a triangle (called Unitarity Triangle). The measurement of the parameters of the triangle is a powerful test of the Standard Model description of the CP violation. This thesis tries to measure the weak phase 2beta+ gamma through the B0 -> D+ K0 Pi- decays. Respect to the two body decays B0 -> D(*)+ Pi- and B0 -> D+ Rho- presently used for the measurement of the same weak phase, the B0 -> D+ K0 Pi- decays should show up a larger CP asymmetry and does not rely on any theoretical assumption. After a review of all the methods for the measurement of 2beta+gamma, the thesis presents the results of a feasibility study of the measurement with the B0 -> D+ K0 Pi- decays . In a second part, the analysis performed on 316 fb-1 of data collected by the BaBar detector at the B-factory PEP2 is presented, from the selection of the events to the time-dependent Dalitz fit technique used in order to extract the weak phase 2beta+gamma as well as the amplitudes and phases of the intermediate resonances contributing to the decay. The result of the analysis gives the following estimation: 2beta+gamma = 89 +/- 53(stat) +23-14(syst) degrees with an irreducible ambiguity of 180 degrees.

The authors presented evidence for the decay {bar B}° --> D*°{bar K}° as well as new measurements of the branching fractions for the decays {bar B}° --> D°{bar K}° and D°{bar K}*°. Their measurements are in agreement with the expectation derived from a cited reference and with previous measurements. They use the central value of their measurement for B({bar B}° --> {bar D}°K*°) and obtain [tau]
