We point out the peculiar form of the gravitational wave signal expected from a gas of particles carry spin-3/2 produced during preheating. Given the very few ways that gravitinos can manifest themselves in an experimentally observable way, we stress the importance of improving the sensitivity of ultrahigh frequency detectors in the future. This review is based on work that appeared in Ref. 1.

来自自旋 3/2 场的高频引力波

我们指出了在预热过程中产生的粒子气体携带自旋 3/2 的引力波信号的特殊形式。鉴于引力子可以通过实验观察到的方式表现出来的方式非常少，我们强调未来提高超高频探测器灵敏度的重要性。这篇评论基于参考文献中出现的工作。1.
