Programme of Research in Experimental Particle Physics at the University of Warwick, 2006-2011

拟议的研究范围包括两个不同的领域：包含美夸克的粒子物理学和中微子物理学。我们的目标是在BABAR实验中进一步研究美介子对物质/反物质不对称性（CP违逆）的影响。这很重要，因为我们已经证明了低能CP破坏的主要来源与CP破坏的标准模型机制是一致的。然而，宇宙学的考虑表明，自然界中应该有其他的CP违反源，所以我们的目标是用美介子进行进一步的敏感测试，以看看是否有任何证据表明自然界中存在其他CP违反源。2）. 中微子性质的解释。它们是非常轻的中性粒子，例如，由太阳发射，在放射性衰变中。最近发现它们是振荡的。从一种类型转化为另一种，当他们繁殖。我们建议建立T2K实验的一部分，旨在确定这种行为的细节。特别是，它旨在建立介子中微子和电子中微子之间振荡的速率和程度，并得出中微子质量的相关信息。我们还建议继续研究和开发COBRA实验，旨在识别CdZnTe中的中微子双β衰变。这将提供有关中微子绝对质量尺度的信息，并将中微子确定为马约拉纳粒子，相当于它们自己的反粒子。我们还将继续研究和开发未来的中微子工厂，以及中微子绝对质量的新测量方法。

The scope of the proposed research lies in two distinct areas: the physics of particles containing the beauty quark, and the physics of neutrinos: 1). We aim to further our research into matter/anti-matter asymmetry (CP Violation) with Beauty mesons at the BABAR experiment. This is important, because we have shown that the leading source of CP violation at low energies is consistent with the Standard Model mechanism of CP violation. However, cosmological considerations indicate that there should be other sources of CP violation in Nature, so we aim to make further sensitive tests with beauty mesons, in order to see if any evidence for additional sources of CP violation in Nature may appear here. 2). The elucidation of the properties of neutrinos. These are very light, neutral particles which are emitted, for example, by the sun, and in radioactive beta decay. They have recently been found to oscillate, ie. transmute from one type to another, while they propagate. We propose to build part of the T2K experiment, which aims to determine the details of this behaviour. In particular, it aims to establish the rate and extent of oscillations between muon- and electron-neutrinos, and to derive related information on neutrino masses. We also propose to continue research and development on the COBRA experiment, which aims to identify neutrinoless double beta decays in CdZnTe. This would provide information on the absolute mass scale of neutrinos and establish the neutrinos as Majorana particles, equivalent to their own anti-particles. We will also continue research and development on a future neutrino factory, and on a new measurement of the absolute mass of the neutrino.
