非粒子真空中的规范对称性恢复

Gauge symmetry restoration in the un-particle vacuum

Patricio Gaete, Euro Spallucci

摘要:

本文研究了基本粒子的电弱标准模型之外的一些“新物理学”对希格斯真空的影响。我们考虑了非粒子和量子引力诱导效应。我们发现即使希格斯场的v.e.v.不为零,规范相互作用保持其长程特性,导致有效的规范对称性恢复。接下来,通过使用一个基于物理的替代通常的威尔逊圈的方法,我们研究了量子引力诱导的最小长度对非粒子扇区中的物理可观察性的影响。因此,我们得到了一个由汇合超几何函数描述的紫外有限相互作用能。该结果显示出与其标准对应物的显著定性偏离。

英文摘要:

In this note we investigate the impact of some "new-physics", beyond the electro-weak Standard Model of elementary particles, on the Higgs vacuum. We consider both un-particle and quantum gravity induced effects. We find that even if the Higgs field takes a non-vanishing v.e.v., gauge interaction keeps its long range character leading to an effective gauge symmetry restoration. Next, by using a physically-based alternative to the usual Wilson loop approach, we examine the effect of a quantum gravity induced minimal length on a physical observable in the un-particle sector. As a consequence, we obtain an ultraviolet finite interaction energy described by a confluent hyper-geometric function. This result displays a marked qualitative departure from its standard counterpart.
