标题： The strong $ρNN$ coupling derived from QCD

摘要： 我们研究了夹在真空和ρ介子态之间的两个核子流的两点关联函数。 同时推导出了光锥QCD求和规则，适用于 $\rho NN$ 的矢量和张量耦合。 通过关于两个外动量 $p_1^2$ 和 $p^2_2=(p-q)^2$ 的双Borel变换，清晰地减去了激发态和连续区的贡献。 我们的结果是：$g_\rho =(2.5\pm 0.2)$，\$\kappa _\rho = (8.0\pm 2.0)，与核力中使用的值非常一致。 显示英文摘要

摘要： We study the two point correlation function of two nucleon currents sandwiched between the vacuum and the rho meson state. The light cone QCD sum rules are derived both for $\rho NN$ vector and tensor couplings simultaneously. The contribution from the excited states and the continuum is subtracted cleanly through the double Borel transform with respect to the two external momenta, $p_1^2$, $p^2_2=(p-q)^2$. Our results are $g_\rho =(2.5\pm 0.2)$, $\kappa_\rho =(8.0\pm 2.0), in good agreement with the values used in the nuclear forces.
