类矢量多重态模型中的大Tau和Tau中微子电偶极矩

Large Tau and Tau Neutrino Electric Dipole Moments in Models with Vector Like Multiplets

Tarek Ibrahim, Pran Nath

摘要:

结果表明,在矢量多重态模型中,τ轻子的电偶极矩可以由混合产生,其大小比标准模型的预测大几个数量级。τ轻子的EDM产生于W、电荷伴子、中性伴子、slepton、镜像轻子和镜像slepton交换的环。狄拉克τ中微子的EDM也是根据涉及W、电荷、镜轻子和镜轻子交换的循环计算的。一个数值分析,它示出的EDMs的τ轻子和τ中微子的谎言只是一对夫妇的数量级低于目前的实验的灵敏度可以实现。因此,该模型的预测是可测试的改进实验的EDM的τ和τ中微子。

英文摘要:

It is shown that the electric dipole moment of the tau lepton several orders of magnitude larger than predicted by the standard model can be generated from mixings in models with vector like mutiplets. The EDM of the tau lepton arises from loops involving the exchange of the W, the charginos, the neutralinos, the sleptons, the mirror leptons, and the mirror sleptons. The EDM of the Dirac tau neutrino is also computed from loops involving the exhange of the W, the charginos, the mirror leptons and mirror sleptons. A numerical analysis is presented and it is shown that the EDMs of the tau lepton and of the tau neutrino which lie just a couple of orders of magnitude below the sensitivity of the current experiment can be achieved. Thus the predictions of the model are testable in improved experiment on the EDM of the tau and of the tau neutrino.
