Probes of New Physics in the Era of High Luminosity Flavor Experiments

我们建议调查和改进探针的物理学超越标准模型，使用风味的观测量，这是专为时代的LHCb运行2和贝儿II。我们有充分的理由相信，标准模型是一个不完整的理论，在基础水平上还有更多的发现。不久的将来，高光度实验将使我们能够以前所未有的实验精度对新物理进行测试，直到非常高的尺度。为了充分利用这些，重要的是理论精度不落后于实验的进步，否则，我们对数据的解释会受到理论方法的不确定性的限制。我们建议以互补的方式改进现有的理论方法，以追求识别新物理的模式。为此，我们计划开展以下工作：i）在CKM矩阵的幺正性破坏测试中解释同位旋破缺，ii）在粲CP破坏中同位旋破坏新物理，iii）轻子味非普适性和iv）极化测量，这使得能够测试具有超越标准模型的洛伦兹结构的算子。

We propose to investigate and improve probes of physics beyond the Standard Model using flavor observables which are tailored to the era of LHCb Run 2 and Belle II. There are very solid reasons to believe that the Standard Model is an incomplete theory and that there is more to discover at the fundamental level.The near future high luminosity flavor experiments will enable us to perform tests for new physics up to very high scales with unprecedented experimental precision. In order to fully benefit from these, it is important that the theoretical precision does not fall behind the experimental advancements, otherwise, our interpretation of the data is bounded by the uncertainties of the theoretical methods.We propose to improve the available theoretical methods in the pursuit of identifying patterns of new physics in a complementary way. To that end we plan to work on i) accounting for isospin breaking in tests of the unitarity violation of the CKM matrix, ii) isospin violating new physics in charm CP violation, iii) lepton flavor nonuniversality and iv) polarization measurements which enable a test of operators with a Lorentz structure beyond the Standard Model.
