非粒子物理中μ子反常磁矩和轻子味破坏τ衰变

Muon Anomalous Magnetic Moment and Lepton Flavor Violating Tau Decay in Unparticle Physics

Andi Hektor, Yuji Kajiyama, Kristjan Kannike

摘要:

我们研究了非粒子物理对μ子g-2和LFV τ衰变过程的影响。标准模型扇区与非粒子之间的LFV相互作用可以解释μ g-2的实验值与标准模型预言值的差异。虽然相同的耦合产生LFV τ衰变,我们发现LFV耦合可以是O(0.1…1)当非粒子算符d_{U}的标度维数> 1.6时,与实验上的LFV τ衰变边界没有冲突.

英文摘要:

We study effects of unparticle physics on muon g-2 and LFV tau decay processes. LFV interactions between the Standard Model sector and unparticles can explain the difference of experimental value of muon g-2 from the Standard Model prediction. While the same couplings generate LFV tau decay, we found that LFV coupling can be of O(0.1 ... 1) without conflict with experimental bounds of LFV tau decay if the scaling dimension of unparticle operator d_{U} > 1.6.
