论文摘要
反应堆中微子实验为研究轴突样颗粒（ALP）提供了丰富的环境。使用核反应堆芯中产生的强光子通量，这些实验具有低于10 MeV的质量的阿尔卑斯山的潜力。我们通过考虑通过Primakoff和类似康普顿的过程以及核转变产生的阿尔卑斯山来探索这些搜索的可行性。这些颗粒随后可以通过轴 - 电动吸收通过逆Primakoff和类似Compton的散射与附近检测器的材料相互作用，或者它们可以腐烂到光子或电子质子质子对中。我们证明，基于反应堆的中微子实验具有测试ALP-Photon耦合和质量的很高潜力，目前仅通过宇宙学和天体物理学观测来探测，从而提供了基于互补的实验室搜索。我们还展示了反应堆设施如何能够在$ \ sim $ meV alp质量范围和ALP-Electron耦合中测试以前未探索的区域，该订单的$ g_ {aee} \ sim 10^{ - 8} $以及alp-nucleon couplings以及$ g_的顺序以及$ g_ a n ann} $ g_ {（1）测试德克萨诺诺邦和Borexino限制以外的地区。
Reactor neutrino experiments provide a rich environment for the study of axionlike particles (ALPs). Using the intense photon flux produced in the nuclear reactor core, these experiments have the potential to probe ALPs with masses below 10 MeV. We explore the feasibility of these searches by considering ALPs produced through Primakoff and Compton-like processes as well as nuclear transitions. These particles can subsequently interact with the material of a nearby detector via inverse Primakoff and inverse Compton-like scatterings, via axio-electric absorption, or they can decay into photon or electron-positron pairs. We demonstrate that reactor-based neutrino experiments have a high potential to test ALP-photon couplings and masses, currently probed only by cosmological and astrophysical observations, thus providing complementary laboratory-based searches. We furthermore show how reactor facilities will be able to test previously unexplored regions in the $\sim$MeV ALP mass range and ALP-electron couplings of the order of $g_{aee} \sim 10^{-8}$ as well as ALP-nucleon couplings of the order of $g_{ann}^{(1)} \sim 10^{-9}$, testing regions beyond TEXONO and Borexino limits.
