非零$θ_{13}$与$μ-τ$对称破缺的CP破坏

Nonzero $θ_{13}$ and CP Violation from Broken $μ-τ$ Symmetry

Asan Damanik

摘要:

非零和相对较大的$θ_{13}$混合角对中微子物理有一些超越标准模型的唯象影响。如果混合角$θ_{13}\neq 0$的结果之一是中微子扇区上的CP破坏的可能性。为了得到非零的$θ_{13}$混合角,我们通过引入一个复参数来破坏遵守$μ-τ$对称性的中微子质量矩阵,并确定Jarlskog不变量作为CP破坏存在的度量.以实验数据为输入,确定了狄拉克相位$δ$随混合角$θ_{13}$的变化关系

英文摘要:

Nonzero and relatively large of $θ_{13}$ mixing angle has some phenomenological consequences on neutrino physics beyond the standard model. One of the consequences if the mixing angle $θ_{13}\neq 0$ is the possibility of the CP violation on the neutrino sector. In order to obtain nonzero $θ_{13}$ mixing angle, we break the neutrino mass matrix that obey $μ-τ$ symmetry by introducing a complex parameter and determine the Jarlskog invariant as a measure of CP violation existence. By using the experimental data as input, we determine the Dirac phase $δ$ as function of mixing angle $θ_{13}$
