最小暗物质及以上的NLO电弱势

NLO electroweak potentials for minimal dark matter and beyond

Kai Urban

摘要:

计算了任意重标准模型多重态在树能级上对$γ$、$W$和$Z$ -交换引起的静电势的单圈修正。我们发现,结果服从“类卡西米尔”标度,使非线性光学修正的潜力的“低能”的性质的电弱规范玻色子。此外,我们还讨论了非线性光学势的唯象性,分析已知的渐近极限,并提供了位置空间中的拟合函数,以便于使用的结果。

英文摘要:

We calculate the one-loop correction to the static potential induced by $γ$, $W$ and $Z$-exchange at tree-level for arbitrary heavy standard model multiplets. We find that the result obeys a "Casimir-like" scaling, making the NLO correction to the potential a "low-energy" property of the electroweak gauge bosons. Furthermore, we discuss the phenomenology of the NLO potentials, the analytically known asymptotic limits and provide fitting functions in position space for easy use of the results.
