标题： From target to projectile and back again: selfduality of high energy evolution

摘要： 我们证明了QCD中高能演化完整的核必须是自对偶的。相关的对偶变换以精确的数学形式表述，并且被表明将电荷密度变换为关于单胶子散射矩阵泛函导数。这种变换交换了高密度和低密度区域。我们演示了原始的JIMWLK核（在大密度下有效）确实与最近在hep-ph/0501198中推导出的完整核的低密度极限对偶。 显示英文摘要

摘要： We prove that the complete kernel for the high energy evolution in QCD must be selfdual. The relevant duality transformation is formulated in precise mathematical terms and is shown to transform the charge density into the functional derivative with respect to the single-gluon scattering matrix. This transformation interchanges the high and the low density regimes. We demostrate that the original JIMWLK kernel, valid at large density is indeed dual to the low denisity limit of the complete kernel derived recently in hep-ph/0501198.
