论文摘要
在目前的工作中，我们研究了$ e^ - e^+ \rightarrowψ（ns）+χ_{cj}（np）$ for $ j = 0,1 $和$ n = 1,2 $，通过领先订单（lo）树级别的$ \ sim o（sim sim phot flual from a a a a em a a a a a a a a a im a a，在$ 4 \ $ 4 $ 4 $ bethe-salpeter方程的框架中，连接两条夸克线（在三角夸克环的部分中），位于质量能量的中心，$ \ sqrt {s} = 10.6 gev。$ $我们试图证明，该过程以四个领先订单$ $ \ sim al \ sim a em（em a em（em）计算的交叉截面BSE方法接近实验数据，这可能主要是由于BSE框架中HADRON内部夸克的运动的持续处理。
In present work we study the production of ground and excited charmonium pairs in $e^- e^+ \rightarrow Ψ(nS)+ χ_{cJ}(nP)$ for $J=0,1$ and $n=1,2$, through leading order (LO) tree-level diagrams $\sim O(α_{em} α_s)$, which proceed through exchange of a virtual photon and an internal gluon line connecting two quark lines (in the triangle quark loop part of the diagram), in the framework of $4\times 4$ Bethe-Salpeter equation, at center of mass energy, $\sqrt{s}=10.6 GeV.$ We have tried to show that the cross sections for this process calculated with use of the four leading order $\sim O(α_{em} α_s)$ diagrams using BSE approach come close to experimental data, which might be mainly due to the consistent treatment of motion of quarks inside the hadrons in the BSE framework.
