非对易时空中的大质量中微子

Massive Neutrino in Non-commutative Space-time

M. M. Ettefaghi, M. Haghighat

摘要:

考虑了基于$SU(3)\times SU(2)\times U(1)$的非交换标准模型。研究了非对易时空中右手中微子的规范变换及其与光子的直接相互作用。我们证明了大质量的狄拉克中微子,通过希格斯机制,不能容纳这种扩展的标准模型,而大质量的马约拉纳中微子是符合规范对称性的模型。研究了非对易标准模型中中微子的电磁性质和色散关系。我们还比较了结果与基于$U(3)\times U(2)\times U(1) $的非交换标准模型。

英文摘要:

We consider the noncommutative standard model based on $SU(3)\times SU(2)\times U(1)$. We study the gauge transformation of right handed neutrino and its direct interaction with photon in the noncommutative space-time. We show that the massive Dirac neutrinos, through the Higgs mechanism, can not accommodate this extension of the standard model; while the massive Majorana neutrinos are consistent with the gauge symmetry of the model. The electromagnetic properties and the dispersion relations for the neutrino in the noncommutative standard model is examined. We also compare the results with the noncommutative standard model based on $U(3)\times U(2)\times U(1) $.
