标题： From Current to Constituent Quarks: a Renormalization Group Improved Hamiltonian-based Description of Hadrons

摘要： 一种将QCD的微扰行为与低能现象学在统一框架中结合的模型被开发出来。 这是通过将相似变换应用于QCD哈密顿量，从而消除紫外截断与任意较低尺度之间的相互作用来实现的。 然后迭代得到在强子能量尺度上的重整化群改进的有效哈密顿量。 该过程保持了QCD的标准紫外行为。 此外，在强子尺度以下，哈密顿量平滑地演化到现象学的低能行为。 该方法的优点是允许辐射修正直接纳入非微扰多体技术中。 它被应用于补充了低能线性禁闭相互作用的库仑规范QCD。 通过Bogoliubov-Valatin变换，分析中包含了非平凡的真空。 最后，该形式被应用于真空间隙方程、夸克凝聚和动态夸克质量。 显示英文摘要

摘要： A model which combines the perturbative behavior of QCD with low energy phenomenology in a unified framework is developed. This is achieved by applying a similarity transformation to the QCD Hamiltonian which removes interactions between the ultraviolet cutoff and an arbitrary lower scale. Iteration then yields a renormalization group improved effective Hamiltonian at the hadronic energy scale. The procedure preserves the standard ultraviolet behavior of QCD. Furthermore, the Hamiltonian evolves smoothly to a phenomenological low energy behavior below the hadronic scale. This method has the benefit of allowing radiative corrections to be directly incorporated into nonperturbative many-body techniques. It is applied to Coulomb gauge QCD supplemented with a low energy linear confinement interaction. A nontrivial vacuum is included in the analysis via a Bogoliubov-Valatin transformation. Finally, the formalism is applied to the vacuum gap equation, the quark condensate, and the dynamical quark mass.
