利用量子干涉鉴别自旋
Discriminating spin through quantum interference
摘要：
许多对层次和自然性问题提出的解决方案假定标准模型粒子有新的“伙伴”场。确定这些新粒子的自旋对于区分各种可能的SM扩展至关重要，但所提出的方法依赖于底层模型。我们提出了一种新的模型无关的方法来测量自旋，它利用了螺旋度态之间的量子干涉。我们证明，这种方法将能够区分标量粒子从更高的自旋状态在ILC，并讨论应用程序更高的自旋和可能的用途在LHC。
英文摘要：
Many of the proposed solutions to the hierarchy and naturalness problems postulate new `partner' fields to the standard model particles. Determining the spins of these new particles will be critical in distinguishing among the various possible SM extensions, yet proposed methods rely on the underlying models. We propose a new model-independent method for spin measurements which takes advantage of quantum interference among helicity states. We demonstrate that this method will be able to discriminate scalar particles from higher spin states at the ILC, and discuss application to higher spins and possible uses at the LHC.
