中微子工厂中非么正混合和CP破坏的探测

Probing non-unitary mixing and CP-violation at a Neutrino Factory

Stefan Antusch, Mattias Blennow, Enrique Fernandez-Martinez, Jacobo Lopez-Pavon

摘要:

低能非幺正轻子混合矩阵是标准模型的许多扩展的一个普遍特征。在这种情况下,未来精确的中微子振荡实验的任务比测量三个混合角和轻子(狄拉克)CP相位更雄心勃勃,即,么正轻子混合矩阵的可达参数一个非幺正混合矩阵有13个影响中微子振荡的参数,其中4个是CP破坏的。在最小么正破坏(MUV)方案中,我们分析了中微子工厂决定或限制非么正轻子混合矩阵参数的可能性,从而检验了轻子扇区中CP破坏的起源.

英文摘要:

A low energy non-unitary leptonic mixing matrix is a generic feature of many extensions of the Standard Model. In such a case, the task of future precision neutrino oscillation experiments is more ambitious than measuring the three mixing angles and the leptonic (Dirac) CP-phase, i.e., the accessible parameters of a unitary leptonic mixing matrix. A non-unitary mixing matrix has 13 parameters that affect neutrino oscillations, out of which four are CP-violating. In the scheme of Minimal Unitarity Violation (MUV) we analyse the potential of a Neutrino Factory for determining or constraining the parameters of the non-unitary leptonic mixing matrix, thereby testing the origin of CP-violation in the lepton sector.
