A search for the rare decay B -> pi l⁺l⁻Wray, Bradley Cole 17 July 2012 (has links)
This thesis presents a search for the rare B meson decay B -> pi l⁺l⁻ (l=e or mu) using 428 fb⁻¹ of data collected at the Upsilon(4S) resonance by the BaBar detector at the PEP-II asymmetric energy e⁺e⁻ storage rings located located at SLAC National Accelerator Laboratory in Menlo Park, California. Four exclusive modes are studied: B⁺ -> pi+ e⁺e⁻, B⁺ -> pi⁺ mu⁺mu⁻, B0 -> pi⁰ e⁺e⁻, and B0 -> pi⁰ mu⁺mu⁻. Branching fraction upper limits at the 90% confidence level are presented for the exclusive modes B⁺ -> pi⁺ mu⁺mu⁻ and B0 -> pi0 mu⁺mu⁻, and the combined mode B -> pi mu⁺mu⁻. / text

Rarity and conservation of Melampyrum sylvaticumDalrymple, Sarah January 2006 (has links)
<i>Melampyrum sylvaticum</i> (small cow-wheat) is a hemiparasitic annual of boreal-montane regions of Europe. The Species Action Plan recommended that in addition to protecting extant populations, by 2010 there should be an additional five populations that have been created with the aim of enhancing greater genetic diversity of the species. Consequently this project was set up in order to provide the ecological knowledge required to meet such targets. There are various management options available to conservationists looking to prevent <i>Melampyrum sylvaticum’s</i> extinction from the UK but from the results of this project it is clear that some methods have drawbacks that should preclude their use. Population augmentation with seeds from other populations is not advised due to the risk of genetic ‘swamping’ or outbreeding depression. Seed amplification would avoid these problems but may introduce different complications by artificially promoting certain genotypes within a population. Population expansion by mimicking ant dispersal is recommended as a way of minimizing density dependent mortality in larger populations but is not suitable in smaller populations. Seed translocation to unoccupied sites is therefore, the best option but the exact details of seed-sourcing and sowing should be guided by the results of the Species Recovery Project in order to avoid predicted limitations. The long-term outlook for <i>M. sylvaticum</i> will depend entirely on whether populations can be created that operate as part of a functioning ecosystem (including pollinating and seed-dispersing insects) with enough demographic and genetic stability to survive predicted climate change.
