Abstract
We present new exclusion bounds obtained at the European X-Ray Free Electron Laser facility (EuXFEL) on axionlike particles in the mass range 10−3eV≲ma≲104eV. Our experiment exploits the Primakoff effect via which photons can, in the presence of a strong external electric field, decay into axions, which then convert back into photons after passing through an opaque wall. While similar searches have been performed previously at a third-generation synchrotron [Yamaji , ], our work demonstrates improved sensitivity, exploiting the higher brightness of x-rays at EuXFEL.

本文提出了在欧洲x射线自由电子激光设备（EuXFEL）上，在质量范围为10−3eV > ma > 104eV的类轴子粒子上得到的新的不相容界。我们的实验利用了普里马科夫效应，光子在强大的外电场下可以衰变成轴子，轴子穿过不透明的墙后又会变成光子。虽然之前在第三代同步加速器上进行了类似的搜索，但我们的工作证明了灵敏度的提高，利用了EuXFEL的更高亮度的x射线。2025年由美国物理学会出版
