论文摘要
在$ {}^{48} $ ca中违反不对称$ a _ {\ rm pv} $的均等的实验确定,杰斐逊实验室的$ {}^{48} $ ca和$ {}^{208} $ pb对于我们如何理解中性和蛋白质在ATOMIC核心内如何安排自己的理解。为了更好地了解这些测量值的影响,我们提出了$ a _ {\ rm pv} $在$ {}^{48} $ ca和$ {}^{208} $ pb中的严格理论研究,并评估了相关的不确定性。我们通过检查这些核中的静电偶极极化性来补充我们的研究。分析是在核能密度功能理论中进行的,并具有量化的输入。我们得出的结论是,$ a _ {\ rm pv} $的同时准确描述在$ {}^{}^{48} $ ca和$ {}^{208} $ pb无法通过我们的模型来实现。这些核中的$α_ {\ rm d} $。
The recent experimental determination of the parity violating asymmetry $A_{\rm pv}$ in ${}^{48}$Ca and ${}^{208}$Pb at Jefferson Lab is important for our understanding on how neutrons and protons arrange themselves inside the atomic nucleus. To better understand the impact of these measurements, we present a rigorous theoretical investigation of $A_{\rm pv}$ in ${}^{48}$Ca and ${}^{208}$Pb and assess the associated uncertainties. We complement our study by inspecting the static electric dipole polarizability in these nuclei. The analysis is carried out within nuclear energy density functional theory with quantified input. We conclude that the simultaneous accurate description of $A_{\rm pv}$ in ${}^{48}$Ca and ${}^{208}$Pb cannot be achieved by our models that accommodate a pool of global nuclear properties, such as masses and charge radii, throughout the nuclear chart, and describe -- within one standard deviation -- the experimental dipole polarizabilities $α_{\rm D}$ in these nuclei.
