在b介子双重衰变中，标量相互作用（有效哈密顿量）与各自的标准模型值相比，可以产生各种实验观测值的显著变化。此外，夸克能级跃迁$b \到$ d \ well ^- \ well ^+$也可用于测试CP违逆。本文将比较研究具有相同夸克能级跃迁（$b \到d \ well ^- \ well ^+$）、$b \到X_d \ well ^- \ well ^+$（包含衰变模式）和独占通道$B_d \到\ well ^- \ well ^+ \gamma$（辐射双光子衰变模式）的两个独立过程中的CP违背。我们将主要对这两种不同通道中CP不对称的标量相互作用进行比较研究。
Scalar interactions (in effective Hamiltonian) can give significant variation of various experimental observables, as comparted to their respective Standard Model values, in dileptonic decays of B-meson. Also the quark level transition $b \to d \ell^- \ell^+$ can be useful to test CP violation. Here we will do comparative study of CP violation in two independent processes, which have the same quark level transition ($b \to d \ell^- \ell^+$), $B \to X_d \ell^- \ell^+$ (the inclusive decay mode) and the exclusive channel $B_d \to \ell^- \ell^+ \gamma$ (radiative dileptonic decay mode). We will mainly focus on the comparative study of scalar interactions on the CP asymmetries in these two different channels.
