从气泡到泡沫:高能强子波函数的稀密演化
From bubbles to foam: dilute to dense evolution of hadronic wave function at high energy
摘要:
导出了弱耦合下强子光锥波函数随能量的演化。我们的推导是有效的,在高和低的部分子密度限制,因此包括两个JIMWLK和KLWMIJ的演变。强子波函数示出的Bogoliubov型运营商,对角化的软胶子部门的光锥哈密顿量的存在下,一个任意的价电荷密度的行动演变。我们发现明确的软以及价自由度的理论,这个运营商的行动。
英文摘要:
We derive the evolution of a hadronic light cone wave function with energy at weak coupling. Our derivation is valid both in the high and the low partonic density limit, and thus encompasses both the JIMWLK and the KLWMIJ evolution. The hadronic wave function is shown to evolve by the action of the Bogoliubov-type operator, which diagonalizes on the soft gluon sector the light-cone hamiltonian in the presence of an arbitrary valence charge density. We find explicitly the action of this operator on the soft as well as the valence degrees of freedom of the theory.
