Shun-Zhi Wang, Shao-Zhou Jiang, Feng-Jun Ge, Qing Wang

摘要:

给出了W ',Z'和中性轻希格斯粒子对称性$SU(2)_1\otimes SU(2)_2\otimes U(1)$的电弱手征拉格朗日量的完整列表.玻色子部分精确到$p^4$阶,物质部分涉及各种费米子表象安排,包括三维Yukawa型和四维规范型算符。给出了规范玻色子和费米子的普适混合和质量。计算了$K^0-\bar{K}^0$、$B_d^0-\bar{B}_{d}^0$、$B_s^0-\bar{B}_{s}^0$系统的质量差和$K$介子的间接CP破坏参数$|ε_K|$的约束。

英文摘要:

The complete list of electroweak chiral Lagrangian for W', Z' and a neutral light higgs with symmetry $SU(2)_1\otimes SU(2)_2\otimes U(1)$ is provided. The bosonic part is accurate up to order of $p^4$, the matter part involving various fermions representation arrangements includes dimension three Yukawa type and dimension four gauge type operators. The universal mixings and masses of gauge boson and fermion are given. Constraints from mass differences for $K^0-\bar{K}^0$, $B_d^0-\bar{B}_{d}^0$, $B_s^0-\bar{B}_{s}^0$ systems and indirect CP violation parameter $|ε_K|$ for $K$ mesons are evaluated.
