Book excerpt: We summarize results on a number of observations of penguin dominated radiative decays of the B meson. Such decays are forbidden at tree level and proceed via electroweak loops. As such they may be sensitive to physics beyond the standard model. The observations have been made at the BaBar experiment at PEPII, the asymmetric B factory at SLAC.

Book excerpt: Electroweak penguin decays provide a promising hunting ground for Physics beyond the Standard Model (SM). The decay B 2!X{sub s}[gamma], which proceeds through an electromagnetic penguin loop, already provides stringent constraints on the supersymmetric (SUSY) parameter space. The present data samples of H" x 108 B{bar B} events allow to explore radiative penguin decays with branching fractions of the order of 10−6 or less. In this brief report they discuss a study of B 2!K*ll− decay modes and a search for B 2[gamma] decays.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of the results obtained from the analysis of the B meson decays that involve Radiative Penguin processes, recorded at the BaBar experiment at the Stanford Linear Accelerator Center PEP-II B-Factory, is presented. The physics interest of these processes and their SM prediction are discussed briefly. The most relevant selection techniques used in the analysis are described before quoting the latest results made public by the BaBar collaboration as of July 2003.

Book excerpt: Recent BABAR results on rare B decays involving flavour-changing neutral currents or purely leptonic final states are presented. New measurements of the CP asymmetries in B 2!K*[gamma], B 2!K*2(1430)[gamma], and b 2!s[gamma] are reported, as well as a new measurement of the B 2!K*[gamma] branching fraction. Also reported are updated limits on B 2![mu][nu] and recent measurements of B 2!K(*)ll and b 2!sll. The data sample comprises 123 · 106 [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II ee− storage ring.

Book excerpt: In this article, I review the most recent results in radiative penguin decays from the B factories Belle and BABAR. Most notably, I will talk about the recent new observations in the decays B → ([rho]/[omega]) [gamma], a new analysis technique in b → s[gamma], and first measurements of radiative penguin decays in the B°{sub s} meson system. Finally, I will summarize the current status and future prospects of radiative penguin B physics at the B factories.

Book excerpt: Electromagnetic radiative penguin decays of the B meson were studied with the BaBar detector at SLAC's PEP-II asymmetric-energy B Factory. Branching fractions and isospin asymmetry of the decay B → K*[gamma], branching fractions of B → K*2(1430)[gamma], and a search for B° → [phi][gamma] are presented. The decay rates may be enhanced by contributions from non-standard model processes.

Available in PDF, EPUB and Kindle. Book excerpt: Radiative penguin decays of B mesons are favour-changing neutral current (FCNC) processes, studies of which provide fertile ground for precision tests of the Standard Model. Because such decays must proceed through 1-loop or higher order processes, they are rare and their amplitudes are particularly sensitive to interference from other FCNC interactions beyond the SM. This thesis presents the search for the rare radiative penguin process b -> d gamma, carried out at the BABAR experiment.

Book excerpt: We present recent results from the BABAR Collaboration on radiative decays. These include searches for new physics via measurements of several observables such as the time- dependent CP asymmetry in B0 → K0S[pi]- [pi]+[gamma] exclusive decays, as well as direct CP asymmetries and branching fractions in B → Xs[gamma] and B → Xsl+l- inclusive decays.

Book excerpt: This article gives an overview of the recent searches and measurements of b → d penguin transitions with the BaBar experiment. The branching fraction of these decays in the Standard Model (SM) is expected to be a factor of 10 or more lower than the corresponding b → s penguin transitions, but a deviation from the SM prediction would be an equally striking sign of new physics. The exclusive decay B →?ll is searched by BaBar with no excess over the background found. The BaBar measurement of B → (?,?)? provides the first evidence of B →?+?, {sup c} is in good agreement with the previous Belle results and provides a measurement of.

Book excerpt: Radiative and electroweak penguin decays of B mesons are flavor-changing-neutral-current processes that provide powerful ways to test the Standard Model at the one-loop level, to search for the effects of new physics, and to extract Standard Model parameters such as CKM matrix elements and quark masses. The large data samples obtained by the B-factory experiments BaBar and Belle, together with an intensive theoretical effort, have led to significant progress towards understanding these rare decays. Recent experimental results include the measurements of the b 2!d[gamma] decays B 2[gamma], the observation of B 2!K(*)ll− decays (together with studies of the associated kinematic distributions), and improved measurements of the inclusive B 2!Xs[gamma] rate and photon energy spectrum.

This book was released on 2012-12-02 with total page 1004 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first precision measurements on CP violation in the B system are reported. Both the BELLE and the BABAR collaboration presented, among others, results for sin 2ß with much improved accuracy. Results from the Sudbury Neutrino Observatory, SNO, also deserve to be mentioned. The convincing evidence of solar neutrino oscillations had been presented by SNO prior to the conference; a full presentation was given at the conference. An incredibly precise measurement of the anomalous magnetic moment of the muon is reported, a fresh result from the Brookhaven National Laboratory. Apart from these distinct physics highlights, there are also the first results from the new Tevatron run and from the relativistic heavy ion collider RHIC. Theorists write of our ever better understanding of the Standard Model and of what might lie beyond. Risky as it is to highlight only a couple of exciting subjects, it is merely meantto whet the appetite for further reading.
