论文摘要
嵌入到两-higgs双重模型中的Abelian Dark部门场景在连贯的弹性中微子核心散射（CE $ν$ ns）实验中进行了审查，该实验首先是由2017年的连贯协作衡量的，从那时起，该努力从那时起就进行了持续的努力，并在其中始终释放了IS CSI的数据，该数据是在20222年中的CSI框架。 $ u（1）$量规组在黑暗区域中，与超充电场的非零动力学混合。靶标CSI和液体氩（LAR）的相干数据在单箱和多箱基础上进行处理，以约束多维参数空间，该空间由深度耦合，动力学混合参数和深色光子质量跨越，完全是七个不同的代表性的场景，这些场景也与彼此相比，并与之相比，并与之相交了，并与之相交了。还解决了精制淬灭因子的效果。
Abelian dark sector scenarios embedded into the two-Higgs doublet model are scrutinized within the Coherent Elastic Neutrino-Nucleus Scattering (CE$ν$NS) experiment, which was first measured by the COHERENT Collaboration in 2017 with an ongoing effort to improve it since then and recently released data for the CsI target in 2022. In the theoretical framework, it is assumed that there is a $U(1)$ gauge group in the dark sector with a non-zero kinetic mixing with the hypercharge field. The COHERENT data for the targets CsI and liquid argon (LAr) are treated in both single and multi bin bases to constrain the multi dimensional parameter space, spanned by the dark gauge coupling, kinetic mixing parameter and the dark photon mass, of totally seven different representative scenarios which are also compared and contrasted among each other to find out about the most sensitive one to the data. The effect of refined quenching factor is also addressed.
