项目摘要

Why are the earth, the stars, our galaxy and everything we can see made out of matter? During the big bang, matter and antimatter were created in equal amounts, so where has the antimatter gone? There is no evidence of anti-matter galaxies or other large structures in the universe. These questions lead to a more profound question, given that the matter and antimatter should have destroyed each other; why are we here? These questions have fascinated me since my late teens and were responsible for guiding me into the field of physics and later specialising in particle physics. My career to date has focused on understanding differences between matter and antimatter, which are (almost) perfect mirror images of the other. The programme of research in this proposal aims to study these differences more precisely than ever before, and to look for new differences that are not explained by our current theories and models. In fact, we already know our theories are not a complete description of everything in the universe, and several hints have appeared recently in this field of particle physics. This research plan will provide new inputs to understand whether or not these hints are real effects of just statistical fluctuations. To achieve these goals, the equally exciting challenges of dealing with huge data samples and utilising the latest computing technologies and software must be conquered. These challenges are increasingly common and important in many fields of science, but also to businesses and the wider world.I will perform these exciting measurements using data from the LHCb detector, based on the large hadron collider (LHC) at the CERN laboratory on the French-Swiss border near Geneva. The LHC collides particles, called protons, at incredible energies to produce other particles that we are interested in studying.

为什么地球，星星，我们的银河系以及我们可以看到的一切都是用物质制成的？在大爆炸期间，物质和反物质的数量相等，那么反物质去了哪里？没有证据表明宇宙中有反物质星系或其他大型结构。这些问题导致了一个更深刻的问题，鉴于问题和反物质应该互相破坏。我们为什么在这里？这些问题自从我十几岁以来就让我着迷，并负责引导我进入物理领域，后来又专门研究粒子物理学。迄今为止，我的职业专注于理解物质和反物质之间的差异，这是对方的完美镜像。该提案中的研究计划旨在比以往任何时候都更精确地研究这些差异，并寻找我们当前理论和模型并未解释的新差异。实际上，我们已经知道我们的理论不是对宇宙中所有事物的完整描述，并且最近在这个粒子物理领域中出现了一些提示。该研究计划将提供新的意见，以了解这些提示是否仅仅是统计波动的实际影响。为了实现这些目标，必须征服处理大量数据样本并利用最新计算技术和软件的同样令人兴奋的挑战。这些挑战在许多科学领域都变得越来越普遍，而且对企业和更广阔的世界都很重要。我将使用LHCB探测器的数据进行这些令人兴奋的测量，该数据基于Geneva附近法国西威斯人的CERN实验室的大型强子撞机（LHC）。 LHC在令人难以置信的能量上碰撞颗粒，称为质子，以产生我们对研究感兴趣的其他颗粒。
