Analysis of B Meson Decays to Three Charged Pions

Li, Yao 23 December 2015 (has links)
Decays of B mesons to three-body charmless final states probe the properties of the weak interaction through their dependence on the complex quark couplings in the CKM matrix. They also test dynamical models for hadronic B decays. Based on a sample of 772 million BB pairs collected by the Belle experiment, we present a study of direct CP violation in the decay of charged B to three charged pions. / Ph. D.

A search for the rare decay of a charged B meson into a charged K meson, a neutrino and an anti-neutrino /

Harnois-Déraps, Joachim. January 2006 (has links)
The document describes a search for the rare decay B¯ → K¯vv̄ in a data set of about 230 millions of BB̄ pairs recorded by the BABAR detector at the PEP-II B Factory, via the process e⁺e⁻ → ϒ(4S) → BB̄. The method used selects events in which the B+ meson is fully reconstructed, and looks for a K¯ in the rest of the event. This is accomplished by applying kinematical and topological restrictions that select B¯ → K¯vv̄ events with the largest possible efficiency, while rejecting a maximum amount of background events. The number of background events is estimated from data and from simulated events, while the value of the selection efficiency relies solely on the simulation of B¯ → K¯vv̄ decays in the BABAR detector. These two numbers are required in order to set an upper limit on the branching ratio. We analyze a subset of the data sample and provide an interpretation of the result.

Analysis of radiative decays of charged B mesons to baryonic final states

Strube, Jan, 1978- 09 1900 (has links)
xxvi, 199 p. : ill. (some col.) A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / The abundance of B mesons at B factories opens the door to the search in rare decays for physics outside of the Standard Model. Flavor-changing neutral current transitions proceed only via higher order in the Standard Model, resulting in a b [arrow right] s³y branching fraction of about 3 x 10 -4 , but hypothesized particles could alter the rate significantly. Decays of B mesons that proceed via this electroweak penguin diagram are an interesting example of flavor-changing neutral currents, due to the large number of accessible final states with observables that are sensitive to new processes. This dissertation describes the analyses of such decays B - [arrow right] p ³, B - [arrow right] £ 0 p ³, B - [arrow right] p and B - [arrow right] p using about 350 million B meson pairs recorded by the BABAR detector in the years 2001 through 2006. In addition to the decay rate, the distribution of the invariant mass of the baryon pair is presented, using a method for statistical unfolding. The analysis is the first of these decays at the BABAR experiment and lays the groundwork for future analyses of the branching fractions and angular correlations of b [arrow right] s decays containing A hyperons and other baryons at BABAR or higher luminosity B factories. / Adviser: James E.
