运行耦合下高能QCD饱和的另一种定标方案

An alternative scaling solution for high-energy QCD saturation with running coupling

Guillaume Beuf

摘要:

发现了一种新的近似标度,它与带有运行耦合的Balitsky-Kovchegov方程相容,这与以前已知的运行耦合几何标度不同。导出了相应的渐近行波解。虽然具有不同的标度行为,这两个解决方案是互补的近似相同的通用解决方案,他们成为等价的高能量极限。在小x DIS数据中观察到了新的标度类型。

英文摘要:

A new type of approximate scaling compatible with the Balitsky-Kovchegov equation with running coupling is found, which is different from the previously known running coupling geometric scaling. The corresponding asymptotic traveling wave solution is derived. Although featuring different scaling behaviors, the two solutions are complementary approximations of the same universal solution, and they become equivalent in the high energy limit. The new type of scaling is observed in the small-x DIS data.
