论文摘要
我们审查规格不变$ \ Mathcal n = 1 $ supersymmetricmemetric Massive $ U（1）$量规理论与Matter和Stuckelberg Superfields结合。我们将重点放在$ U（1）$ vector Superfield和Stuckelberg Superfield的无数限制下，对物质领域的领先自我能源和顶点校正。我们明确验证该理论是否在无质量极限的情况下是无红的差异。因此，斯塔克伯格机制似乎是处理超对称量子电动力学中红外发散的有效途径。由于这些其他颗粒具有很小的质量，它们可以通过“超轻颗粒”机制作为暗物质候选。
We review gauge invariant $\mathcal N =1$ supersymmetric massive $U(1)$ gauge theory coupled to matter and Stuckelberg superfields. We focus on the leading order self energy and vertex correction to the matter field in the massless limit of both the $U(1)$ vector superfield and the Stuckelberg superfield. We explicitly verify that the theory is infrared divergence free in the massless limit. Hence the Stuckelberg mechanism appears to be the efficient route to handle infrared divergences seen in supersymmetric quantum electrodynamics.Since these additional particles have very small masses they can serve as dark matter candidates through `Ultralight particles' mechanism.
