太阳中$\mathbf{pep}$反应产生的中微子流的估算
The estimation of neutrino flux produced by $\mathbf{pep}$ reactions in the Sun
摘要：
由$p+p+e \rightarrow d+ν_e$反应（\textit{pep}）产生的太阳中微子通量的实验结果在2012年首次由Borexino合作宣布。这个中微子通量明显大于Bahcall和May预测的通量，他们使用两体方法计算这个反应。我们用连续能谱中质子-质子-电子系统的三体模型确定了\textit{pep}反应的速率，并估算了中微子流。我们的结果比Bachall的\textit{et al.}值大25- 40%，并且与核子-核子（$NN$）势的形状有关.此外，计算的通量位于实验数据的置信区间内的情况下，纯吸引势以及潜在的排斥在小的核子之间的距离。
英文摘要：
The experimental result of the solar neutrino flux at one AU produced by the $p+p+e \rightarrow d+ν_e$ reaction (\textit{pep}) was announced for the first time in 2012 by the Borexino collaboration. This neutrino flux was significantly greater than the flux predicted by Bahcall and May, who used two body approaches for calculation of this reaction. We have used the three-body model for the proton-proton-electron system in the continuous spectrum of energy to determine the rate of the \textit{pep} reaction and have estimated the neutrino flux. Our result of the neutrino flux is 25-40\% more than the Bachall \textit{et al.} value and depends on the shape of nucleon-nucleon ($NN$) potential. Moreover, the calculated flux lies within the confidence interval of the experimental data in the case of pure attractive potentials as well as potential having repulsion at small distances between nucleons.
