Book Description
This thesis presents a measurement of the time-dependent asymmetry in the rate of[anti B][sub d][sup 0] versus B[sub d][sup 0] decays to J/[psi]K[sub s][sup 0]. In the context of the Standard Model this is interpreted as a measurement of the CP violation parameter sin(2[beta]). A total of 198[+-]17 B[sub d][sup 0]/[anti B][sub d][sup 0] decays were observed in p[anti p] collisions at[radical]s=1.8 TeV by the CDF detector at the Fermilab Tevatron. The initial B flavor (whether B[sup 0] or[anti B][sup 0]) is determined by a same-side flavor tagging technique. The analysis results in sin(2[beta])=1.8[+-]1.1(stat.)[+-]0.3(syst.). This analysis demonstrates the feasibility of studying CP violation in the B[sup 0]-[anti B][sup 0] system at a hadron collider. By applying the methods used in this analysis, future, higher-statistics experiments should be able to tightly constrain the parameters of the Standard Model.

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
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
We present a measurement of the time-dependent asymmetry in the rate for [anti]B[sup 0][sub d] versus B[sup 0][sub d] decays to J/[psi] K[sup 0][sub S] . In the context of the Standard Model this is interpreted as a measurement of the CP-violation parameter sin(2[beta]). A total of 198 [+-] 17 B[sup 0][sub d]/[anti B][sup 0][sub d] decays were observed in p[anti p] collisions at ps = 1:8 TeV by the CDF detector at the Fermilab Tevatron. The initial b-flavor is determined by a same side avor tagging technique. Our analysis results in sin(2[beta]) = 1:8 [+-] 1:1(stat) [+-] 0:3(syst).

Book Description
This dissertation presents a measurement of the time-dependent CP-violating asymmetries in the neutral B-meson system performed with data collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data sample used consists of 29.7 fb[sup -1] collected at the[Upsilon](4S) resonance and 3.9 fb[sup -1] collected off-resonance. We analyze three samples of fully-reconstructed B-meson decays: a sample of decays to CP eigenstates in the modes J/[psi] K[sub s][sup 0], [psi](2S) K[sub s][sup 0], [chi][sub cl] K[sub s][sup 0], and J/[psi] K*[sup 0] (822 events); as well as both charged (14304 events) and neutral (10457 events) B decays to flavor-eigenstates including D[sup (*)] and[pi]/[rho]/[alpha][sub 1]. In all cases, the proper decay time difference between the reconstructed B-meson and the recoiling B-meson is determined by measuring the separation of the two decay vertices. Furthermore, the flavor of the recoiling B-meson is tagged using a neural network algorithm. We use the flavor-eigenstate samples to calibrate both the vertexing and tagging performance. We measure the amplitude of the CP asymmetry, sin2[beta]= 0.61[+-] 0.14(stat)[+-] 0.06(syst). These results indicate the existence of indirect CP violation in the B-meson system.
