两个轻矢量介子电产生过程中BFKL核的共线改进

Collinear improvement of the BFKL kernel in the electroproduction of two light vector mesons

Francesco Caporale, Alessandro Papa, Agustin Sabio Vera

摘要:

我们测试的性能的RG改进的内核在确定的物理过程,两个光矢量介子的电生的振幅,在BFKL方法在下一个领先的近似(NLA)。我们发现,可以实现一个平滑的行为的振幅与质心的能量,设置重正化和能量尺度出现在subleading条款的值更接近的运动学尺度的过程比在基于未改进的内核的方法。

英文摘要:

We test the performance of a RG-improved kernel in the determination of the amplitude of a physical process, the electroproduction of two light vector mesons,in the BFKL approach at the next-to-leading approximation (NLA). We find that a smooth behavior of the amplitude with the center-of-mass energy can be achieved, setting the renormalization and energy scales appearing in the subleading terms to values much closer to the kinematical scales of the process than in approaches based on unimproved kernels.
