We report measurements of branching fractions for charged and neutral B -> ncK decays, and determine the nc mass and width. The results are based on an analysis of 29.1 fb-1 of data collected by the Belle detector at KEKB. We also report a measurement of the CP violation parameter sin©ı1) ימ 0ֶ ־> מד0ּף גבףוה ןמ במ במבלשףיף ןז ב 78 זג־1 ןז הבפב ףבםנלו. �ו עונןעפ פטו ןגףועצבפיןמ ןז פטו הודבש םןהו ״ֶ־־> ננ״ּ גבףוה ןמ במ במבלשףיף ןז 29.4 זג ־1 ןז הבפב דןללודפוה גש פטו וֶללו הופודפןע בפ .ֶֹּּ �טיף יף פטו זיעףפ ורבםנלו ןז ב ג ־> ף פעבמףיפיןמ קיפט גבעשןמף ימ פטו זימבל ףפבפו. �טו ננ םבףף ףנודפעץם ימ פטיף הודבש יף ימדןמףיףפומפ קיפט נטבףו ףנבדו במה יף נובכוה בפ לןק םבףף. �טו געבמדטימח זעבדפיןמ זןע פטיף הודבש יף םובףץעוה פן גו ֶ" -> ppK") = ڃڋٽۋۍڲۍڀچڃچ ڂڅڃڍپ ٲ څڃډٽۋ�ۋۍپپ ۓ چڅڂڊڃ ڨڶ ڲڹۋۄ ۊڶۅۄۊۍ ێۅۅڶۊ ڹڻھڻۍۋ ڷۄۊ ۍںڶ ڵڶڴڲ�ۋ ږڅ ڂڒ ۅۅڞۋ ڲۀڵ ږٲ ڂڒ ۅۅ�ڃٲ

This thesis describes the thorough analysis of the rare B meson decay into φ K* on data taken by the Belle Collaboration at the B-meson-factory KEKB over 10 years. This reaction is very interesting, because it in principle allows the observation of CP-violation effects. In the Standard Model however, no CP violation in this reaction is expected. An observation of CP asymmetries thus immediately implies new physics. This thesis presents an amplitude analysis of this decay and the search for CP violation in detail and discusses methods to solve related problems: The quantification of multivariate dependence and the improvement of numeric evaluation speed of normalization integrals in amplitude analysis. In addition it provides an overview of the theory, experimental setup, (blind) statistical data analysis and estimation of systematic uncertainties.

The authors present measurements of the CP-violation parameters S and C for the radiative decay B° →?K{sub S}°?; for B →?K? they also measure the branching fractions and for B →?K+? the time-integrated charge asymmetry?{sub ch}. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 465 x 106 B{bar B} pairs produced in e+e− annihilation. The results are S = -0.18{sub -0.46}{sup +0.49} ± 0.12, C = -0.32{sub -0.39}{sup +0.40} ± 0.07,?(B° →?K°?) = (7.1{sub -2.0}{sup +2.1} ± 0.4) x 10−6,?(B+ →?K+?) = (7.7 ± 1.0 ± 0.4) x 10−6, and?{sub ch} = ( -9.0{sub -9.8}{sup +10.4} ± 1.4) x 10−2. The first error quoted is statistical and the second systematic.

We present measurements of CP-violating asymmetries and branching fractions for the decays B{sup +} {yields} {omega}{pi}{sup +}, B{sup +} {yields} {omega}K{sup +}, and B{sup 0} {yields} {omega}K{sup 0}. The data sample corresponds to 232 million B{bar B} pairs produced by e{sup +}e{sup -} annihilation at the {Upsilon}(4S) resonance. For the decay B{sup 0} {yields} {omega}K{sub s}{sup 0}, we measure the time-dependent CP-violation parameters S = 0.51{sub -0.39}{sup +0.35} {+-} 0.02, and C = -0.55{sub -0.26}{sup +0.28} {+-} 0.03. We also measure the branching fractions, in units of 10{sup -6}, {Beta}(B{sup +} {yields} {omega}{pi}{sup +}) = 6.1 {+-} 0.7 {+-} 0.4, {Beta}(B{sup +} {yields} {omega}K{sup +}) = 6.1 {+-} 0.6 {+-} 0.4, and {Beta}(B{sup 0} {yields} {omega}K{sup 0}) = 6.2 {+-} 1.0 {+-} 0.4, and charge asymmetries {Alpha}{sub ch}(B{sup +} {yields} {omega}{pi}{sup +}) = -0.01 {+-} 0.10 {+-} 0.01 and {Alpha}{sub ch}(B{sup +} {yields} {omega}K{sup +}) = 0.05 {+-} 0.09 {+-} 0.01.
