非粒子物理与Z极上的A_{FB} ^b

Unparticle Physics and A_{FB}^b on the Z pole

Mingxing Luo, Wei Wu, Guohuai Zhu

摘要:

本文尝试用非粒子扇区来解决LEP数据中b夸克前后不对称性的3σ异常。对于除某些特定区域外的大部分参数空间,当考虑到其他LEP观测量的约束时,异常不能被合理地解释。

英文摘要:

An attempt has been made to address the 3σanomaly of the forward-backward asymmetry of b quark in LEP data via an unparticle sector. For most part of the parameter space except certain particular regions, the anomaly could not be explained away plausibly, when constraints from other LEP observables are taken into account.
