论文摘要
我们证明了耦合群集理论的能力，可以使用手性有效场理论中的相互作用来计算$^4 $ HE和$^{16} $ o nuclei的库仑和规则。我们执行几项检查，包括一些$^4 $ HE的几个基准测试。我们提供了质量污染中心污染的分析，我们可以安全地删除。然后，我们将文献中获得的其他理论结果和实验数据进行比较，并获得公平的协议。这是启动从第一原理计算中微子核相互作用的程序的第一步，也是必要的一步，并通过最先进的理论支持实验性的长基线中微子程序，该理论可以达到中等的核核。
We demonstrate the capability of coupled-cluster theory to compute the Coulomb sum rule for the $^4$He and $^{16}$O nuclei using interactions from chiral effective field theory. We perform several checks, including a few-body benchmark for $^4$He. We provide an analysis of the center-of-mass contaminations, which we are able to safely remove. We then compare with other theoretical results and experimental data available in the literature, obtaining a fair agreement. This is a first and necessary step towards initiating a program for computing neutrino-nucleus interactions from first principles and supporting the experimental long-baseline neutrino program with a state-of-the-art theory that can reach medium-mass nuclei.
