论文摘要
我们在QCD的Sakai-Sugimoto-witten全息模型的背景下研究孤子。在较大的hooft耦合极限中，平坦的空间instantons对重的Baryons进行了大致描述。我们通过用零模式将BPST Instanton变形，并获得有效动作的转向校正来提供ANSATZ。我们还考虑集体坐标的量子机械描述。校正项似乎是对哈密顿式电势的扰动，因此我们可以得出对重子的质谱的一阶校正。
We study solitons in the context of Sakai-Sugimoto-Witten holographic model of QCD. In the large 't Hooft coupling limit, flat space instantons give an approximate description of baryons. We provide an ansatz through deforming the BPST instanton by zero modes and obtain a subleading correction to the effective action. We also consider the quantum mechanical description of the collective coordinates. The correction term appears as a perturbation to the potential of the Hamiltonian and hence we can derive a first order correction to the mass spectrum of baryons.
