论文摘要
我们研究了通过均匀磁场及其检测方案中振荡轴（或类似轴突的粒子）暗物质激发的直接辐射。我们杂质得出了圆柱均匀磁场的轴突诱导的辐射功率的分析表达。在长波极限中，辐射功率与B场体积的平方和Axion质量$ M_A $成正比，而它振动为接近短波极限，峰值功率与圆柱磁场的侧面区域成正比，且峰值功率与$ M_A^{-2} $成比例。最大功率定位在质量$ m_a \ sim \ frac {3π} {4r} $的固定半径$ r $。基于这种功率的这种特征，我们讨论了一个方案，以检测质量范围$ 1-10^4 $ \，NEV的轴，其中四个不同带宽的检测器围绕B场。在典型参数值下，$ M_A \ Lessim1 \，μ$ eV的预期灵敏度远远超过了现有的约束。
We study the direct radiation excited by oscillating axion (or axion-like particle) dark matter in a homogenous magnetic field and its detection scheme. We concretely derive the analytical expression of the axion-induced radiated power for a cylindrical uniform magnetic field. In the long wave limit, the radiation power is proportional to the square of the B-field volume and the axion mass $m_a$, whereas it oscillate as approaching the short wave limit and the peak powers are proportional to the side area of the cylindrical magnetic field and $m_a^{-2}$. The maximum power locates at mass $m_a\sim\frac{3π}{4R}$ for fixed radius $R$. Based on this characteristic of the power, we discuss a scheme to detect the axions in the mass range $1-10^4$\,neV, where four detectors of different bandwidths surround the B-field. The expected sensitivity for $m_a\lesssim1\,μ$eV under typical-parameter values can far exceed the existing constraints.
