论文摘要
我们讨论了Extp X射线望远镜的潜力，特别是其光谱焦点阵列（SFA），大面积检测器（LAD）和宽场监视器（WFM），以检测来自KeV规模衰减暗物质的信号。我们表明，EXTP的敏感性足以改善中微子中微子最小值（$ν$ MSM）的混合角度的现有约束，在2-50 KEV的深色物质质量范围内，假设系统不确定性的水平为1％。我们断言，EXTP将能够探测$ν$ MSM参数的不可访问范围，并作为衰败暗物质搜索的雅典娜任务的先驱。
We discuss the potential of the eXTP X-ray telescope, in particular its Spectroscopic Focusing Array (SFA), Large Area Detector (LAD) and Wide Field Monitor (WFM) for the detection of a signal from keV-scale decaying dark matter. We show that the sensitivity of the eXTP is sufficient to improve existing constraints on the mixing angle of the neutrino Minimal extension of the Standard Model ($ν$MSM) by a factor of 5-10 within the dark matter mass range 2-50 keV, assuming 1% level of systematic uncertainty. We assert that the eXTP will be able to probe previously inaccessible range of $ν$MSM parameters and serve as a precursor for the Athena mission in decaying dark matter searches.
