用LHCb搜索Bs-Bsbar系统中的CP破坏

Search for CP violation in the Bs - Bsbar system with LHCb

D. van Eijk

摘要:

在$B^0_s \to J/ψϕ$等衰变中确定混合诱导的CP破坏不对称性是LHCb实验的关键目标之一。它的值在标准模型中被预测为非常小,但在新物理学的许多模型中可以显着增强。通过对衰减$B^0_s \to J/ψϕ$进行风味标记、随时间变化的角度分析,将介绍精确确定该阶段的步骤,并使用2010年和2011年运行前几个月收集的数据,显示该测量计划的第一批结果。结果也将显示,并讨论前景,从相关的测量。

英文摘要:

The determination of the mixing induced CP-violating asymmetry in decays such as $B^0_s \to J/ψϕ$ is one of the key goals of the LHCb experiment. Its value is predicted to be very small in the Standard Model but can be significantly enhanced in many models of New Physics. The steps towards a precise determination of this phase with a flavour-tagged, time-dependent, angular analysis of the decay $B^0_s \to J/ψϕ$ will be presented, and first results shown from this measurement programme, using data collected in 2010 and the early months of the 2011 run. Results will also be shown, and prospects discussed, from related measurements.
