论文摘要
我们认为是鬼粒子（ALP）的可能性，该粒子是一个幽灵，具有错误的符号动力学和质量术语。这样的ALP可以作为具有更高衍生二次术语的理论中普通粒子的伴侣。我们计算光闪烁的壁壁实验中的光子再生概率，并表明这种幽灵的ALP的存在原则上可以引起可辨别的效果。
We consider the possibility of an axion-like particle (ALP) that is a ghost, with wrong-sign kinetic and mass terms. Such an ALP can arise as the partner to an ordinary particle in theories with higher-derivative quadratic terms. We compute the photon regeneration probability in light-shining-through-wall experiments and show that the presence of such a ghostly ALP can lead, in principle, to discernible effects.
