Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model (SM) explains CP violation in terms of the CKM matrix. The BABAR experiment was designed mainly to test the CKM model in B decays. B decays that proceed through b → s loop diagrams, of which B → KKK decays are an example, are sensitive to new physics effects that could lead to deviations from the CKM predictions for CP violation. We present studies of CP violation in the decays B+ → K+K-K+, B+ → KS0KS0K+, and B0 → K+K-KS0, using a Dalitz plot amplitude analysis. These studies are based on approximately 470 million B$\bar{B}$ decays collected by BABAR at the PEP-II collider at SLAC. We perform measurements of time-dependent CP violation in B0 → K+K-KS0, including B0 → [Phi]KS0. We measure a CP-violating phase [beta]eff ([Phi]KS0) = 0.36 ± 0.11 ± 0.04 rad., in agreement with the SM. This is the world's most precise measurement of this quantity. We also measure direct CP asymmetries in all three decay modes, including the direct CP asymmetry ACP ([Phi]K+) = (12.8 ± 4.4 ± 1.3)%, which is 2.8 sigma away from zero. This measurement is in tension with the SM, which predicts an asymmetry of a few percent. We also study the resonant and nonresonant features in the B → KKK Dalitz plots. We find that the hypothetical scalar fX(1500) resonance, introduced by prior analyses to explain an unknown peak in the mKK spectrum, cannot adequately describe the data. We conclude instead that the fX(1500) can be explained as the sum of the f0(1500), f'2(1525), and f0(1710) resonances, removing the need for the hypothetical fX(1500). We also find that an exponential nonresonant model, used by previous analyses to describe the broad nonresonant feature seen in B → KKK decays, cannot fully model the data. We introduce a new nonresonant model that contains more free parameters, allows for phase motion, and contains both S-wave and P-wave components.
Book Synopsis CP Violation in the Hadronic Ks Meson Decays by : Michał Silarski
Download or read book CP Violation in the Hadronic Ks Meson Decays written by Michał Silarski and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discrete symmetries as parity P, charge conjugation C and time reversal T, as well as their combinations such as CP and CPT play a fundamental role in particle physics. The CP symmetry violation was discovered unexpectedly in 1964 during the regeneration studies of the neutral K mesons, and result in a far-reaching consequences. In the framework of the Standard Model it implies the existence of the third generation of quarks. Moreover, it is a very important mechanism which could have an essential contribution to the asymmetry between matter and antimatter in the Universe. Parameters describing CP violation in neutral kaon decays were measured with a good precision and at present the main experimental effort is focused on studies of the neutral B and D meson systems. However, there are still several interesting open issues in the kaon physics, like rare Ks meson decays. This work is focused on the measurement of the rare CP violating Ks 3 0 decay branching ratio based on the data sample gathered with the KLOE detector operating at the -factory DA NE in the Italian National Center for Nuclear Physics in Frascati.

Book excerpt: After a brief review of the puzzling light scalar meson sector of QCD, a brief summary will be given of a paper concerning radiative decays involving the light scalars. There, a simple vector meson dominance model is constructed in an initial attempt to relate a large number of the radiative decays involving a putative scalar nonet to each other. As an application it is illustrated why a[sub 0](980)-f[sub 0](980) mixing is not expected to greatly alter the f[sub 0]/a[sub 0] production ratio for radiative[phi] decays.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents studies of CP violation in the decays B0--> K+K-Ks, B+--> K+K-K+, and B+--> KsKsK+, using a Dalitz plot amplitude analysis. These studies are based on data from the BaBar experiment at PEP-II at SLAC. Among the significant results are the world's most precise measurements of time-dependent CP-violation in B0--> phi Ks and direct CP violation in B+--> phi K+. The latter is measured to deviate from zero by 2.8 standard deviations, in tension with the Standard Model expectation. We also study the resonant and nonresonant substructure of B--> KKK decays, and find evidence against the previously hypothesized resonance dubbed the "fX(1500)."

Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model (SM) of particle physics successfully describes all of the observed interactions of the fundamental particles (with the exception of non-zero neutrino mass). Despite this enormous success, the SM is widely viewed as an incomplete theory. For example, the size of the asymmetry between matter and antimatter is not nearly large enough to account for the abundance of matter observed throughout the universe. It is thus believed that as-yet-unknown physical phenomena must exist that introduce new asymmetries between matter and antimatter. In this thesis, by studying decays that happen only rarely in the SM, we make measurements of asymmetries between matter and antimatter that are potentially sensitive to the existence of processes beyond the SM. At the PEP-II asymmetric-energy B Factory at SLAC, electrons and positrons are collided at the [Upsilon](4S) resonance to create pairs of B mesons. The BABAR detector is used to measure the subsequent decay products. Using 383 million [Upsilon](4S) 2!B$\bar{B}$ decays, we study the decay B0 2!K+K-K0. In the SM, this decay is dominated by loop amplitudes. Asymmetries between matter and antimatter (CP asymmetries) are extracted by measuring the time-dependence of the complex amplitudes describing the B0 and $\bar{B}$0 decays as functions of their kinematics. The interference between decays with and without the mixing of neutral B mesons allows for the measurement of the angle [beta]eff, which is a measure of CP violation. We also measure the direct CP asymmetry ACP. Data samples reconstructed from three K0 modes (KS0 2![pi]+[pi]-, KS0 2![pi]0[pi]0, and KL0) are fit simultaneously. They find ACP = -0.015 ± 0.077 ± 0.053 and [beta]eff = 0.352 ± 0.076 ± 0.026 rad, corresponding to a CP violation significance of 4.8[sigma]. A second solution near [pi]/2-[beta]eff is disfavored with a significance of 4.5[sigma]. In a subsequent fit to the region with mK+K-> 1.1 GeV/c2, they find ACP = -0.054 ± 0.102 ± 0.060 and [beta]eff = 0.436 ± 0.087-0.031+0.055 rad, excluding the possibility that [beta]eff = 0 at 5.1[sigma]. They use the data with msub K+K-

This book was released on 2006 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of CP-violation in weak interactions, discovered in 1964 in decays of neutral kaons, receives a simple and elegant explanation in the Standard Model with three generations of quarks. Indeed, in this model the common source of CP-asymmetry phenomena is represented by a simple complex phase in the unitary matrix (the Cabibbo-Kobayashi-Maskawa matrix) describing the charged weak couplings of the quarks. This simple scheme has never received an accurate validation, because the phenomenological parameters determined from measurements of CP-violation in kaons decays are related to the fundamental parameters of the theory in a complex way, sensitive to large theoretical uncertainties. On the contrary, decays of neutral B mesons like B{sup 0} {yields} J/{psi} K{sub S}{sup 0} represent a unique laboratory to test the predictions of the theory because they are expected to show significant CP-violation effects, the magnitude of which is cleanly related to the Standard Model parameters. Thus experimental facilities have been built with the purpose of performing extensive studies of B decays. The BABAR experiment is operating at one of these facilities, at the Stanford Linear Accelerator Center. It is collecting data at the PEP-II asymmetric e{sup +}e{sup -} collider (E{sub e{sup -}} = 9.0 GeV; E{sub e{sup +}} = 3.1 GeV), a high-luminosity accelerator machine (L = 3 x 10{sup 33} cm{sup -2}s{sup -1}). The center-of-mass energy (10.58 GeV) of the e{sup +}e{sup -} system at PEP-II allows resonant production of the {Upsilon}(4S), a b{bar b} bound state, which decays almost exclusively in a B{sup 0}{bar B}{sup 0} or a B{sup +}B{sup -} pair. A high-acceptance detector, projected and built by a wide international collaboration, detects and characterizes the decay products of the B mesons. From the analysis of the data collected during the first two years of operation, the BABAR collaboration has established CP-violation in decays of neutral B mesons at the 4.1{sigma} level. Besides the primary goal of CP-violation studies, the high luminosity of PEP-II, coupled with the high acceptance of the BABAR detector, allows competitive studies of the properties of a wide set of B decay modes. In particular, measurements of non-leptonic decays are extremely useful to understand the dynamics of the non-perturbative strong interactions involved in these processes. In this thesis a study of the non-leptonic decay mode B{sup {+-}} {yields} J/{psi}{pi}{sup {+-}} is presented.
