A very important issue in particle physics today is searching for signals of physics beyond the standard model. The B meson system is especially important in that decays of this particle are very sensate to possible novel sources of CP violation that occur in non-standard models. This research will focus on two classes of models which are extensions of the standard model, namely left-right models and multi-Higgs models.One aspect of the proposal will be to formulate new observables or techniques that might be used to help discriminate low energy signals of new physics. CP asymmetries that will be examined include possible decays of the b quark into a strange quark and photon or dilepton pair, as well as decays of the B into J/psi and phi mesons.

粒子物理学中一个非常重要的问题是寻找标准模型之外的物理信号。 B介子系统是特别重要的，因为这种粒子的衰变对发生在非标准模型中的CP破坏的可能的新来源非常敏感。这项研究将集中在两类标准模型的扩展，即左-右模型和多希格斯模型，其中一个方面的建议将是制定新的观测量或技术，可能用于帮助区分新物理的低能信号。 CP不对称性的研究包括B夸克可能衰变为奇异夸克和光子或双轻子对，以及B衰变为J/psi和phi介子。
