论文摘要
FASER是一个有前途的实验之一，它在标准模型之外寻找长寿命的颗粒。在本文中，我们专注于与附加的u（1）量规对称性相关联的深色光子，以及一个标量玻色子，打破了u（1）量规对称性。我们研究了源自U（1）破坏标量衰减的深色光子的敏感性。我们发现，在更广泛的参数空间中，比以前的研究可以预期大量的深色光子特征。
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we focus on dark photon associating with an additional U(1) gauge symmetry, and also a scalar boson breaking this U(1) gauge symmetry. We study the sensitivity to the dark photon originated from U(1)-breaking scalar decays. We find that a sizable number of dark photon signatures can be expected in wider parameter space than previous studies.
