全息QCD的四核子接触相互作用

Four-nucleon contact interactions from holographic QCD

Youngman Kim, Deokhyun Yi, Piljin Yi

摘要:

在全息QCD中,我们用有效手征拉格朗日量计算了四核子相互作用的低能常数。我们从D4-D8模型出发,得到介子-核子相互作用,然后积分出大质量介子,得到四维情况下的四核子相互作用。我们最终得到了两个低能量常数在领先的顺序和七个他们在下一个领先的顺序,这是一致的有效手征拉格朗日。低能常数的值与前五个Kaluza-Klein共振进行评估。

英文摘要:

We calculate the low energy constants of four-nucleon interactions in an effective chiral Lagrangian in holographic QCD. We start with a D4-D8 model to obtain meson-nucleon interactions and then integrate out massive mesons to obtain the four-nucleon interactions in 4D. We end up with two low energy constants at the leading order and seven of them at the next leading order, which is consistent with the effective chiral Lagrangian. The values of the low energy constants are evaluated with the first five Kaluza-Klein resonances.
