內容摘要：
The Standard Model of Particle Physics which describes the behavior of subatomic particles and their interactions, has been extensively tested and confirmed through a wide range of experiments over several decades. Despite its success there are some unsolved mysteries which Standard Model can not address, such as hierarchy problem, Origin of mass specturm, nature of dark matter, lepton flavor non-universality etc. To address these unsolved mysteries one needs to go beyond the Standard Model.
In this talk we will discuss the angular decay distribution of the four-fold Bc → Ds?(→ Dsγ)μ+μ?, and Bc → Ds?(→ Dsπ)μ+μ? decays that proceed through b → sμ+μ? quark level transition. We use the model independent effective Hamiltonian with vector and axial vector new physics operators to formulate the angular observables and study the implications of different latest new physics scenarios, taken from the global fits to all the b → s data, on these observables. Furthermore in this talk we discuss the dark matter candidate via rare B meson decays.
