用反应堆中微子实验探测暗光子

Detecting Dark Photon with Reactor Neutrino Experiments

HyangKyu Park

摘要:

我们建议寻找光$U(1)$暗光子,$A'$,通过与普通光子通过康普顿类过程,$γe^- \rightarrow A' e^-$,在核反应堆中的动力学混合产生的,并通过它们与反应堆中微子实验的活性体积中的材料的相互作用来检测。我们分别从近地天体和TEXONO的实验数据中推导出了$ε~< ~1.3\times 10^{-5}$和$ε~<~2.1\times 10^{-5}$暗光子质量低于1 $\sim$ MeV时$ε$的95%置信度上限,即$A'$-$γ$混合参数$ε$。这项研究证明了核反应堆作为低质量暗光子强通量的潜在来源的适用性。

英文摘要:

We propose to search for light $U(1)$ dark photons, $A'$, produced via kinetically mixing with ordinary photons via the Compton-like process, $γe^- \rightarrow A' e^-$, in a nuclear reactor and detected by their interactions with the material in the active volumes of reactor neutrino experiments. We derive 95\% confidence-level upper limits on $ε$, the $A'$-$γ$ mixing parameter, $ε$, for dark-photon masses below 1$\sim$MeV of $ε~< ~1.3\times 10^{-5}$ and $ε~<~2.1\times 10^{-5}$, from NEOS and TEXONO experimental data, respectively. This study demonstrates the applicability of nuclear reactors as potential sources of intense fluxes of low-mass dark photons.
