光锥QCD在点阵上的表示
Formulating Light Cone QCD on the Lattice
摘要：
给出了格点量子色动力学中依赖于参数$η$的近光锥哈密顿量$H$，参数$η$给出了到光锥的距离。由于真空的动量为零，我们可以从$H$导出一个有效的哈密顿量$H_{eff}$，它的动量只有平方，因此可以用标准方法求解。在极限$η\to 0$下，用变分方法确定了近似的基态波泛函.
英文摘要：
We present the near light cone Hamiltonian $H$ in lattice QCD depending on the parameter $η$, which gives the distance to the light cone. Since the vacuum has zero momentum we can derive an effective Hamiltonian $H_{eff}$ from $H$ which is only quadratic in the momenta and therefore solvable by standard methods. An approximate ground state wave functional is determined variationally in the limit $η\to 0$.
